BIGGER VENUE FOR 1992
BBC ACORN USER SHOW
WEMBLEY Exhibition Centre
will once again he the venue
for the BBC Atom User Show
this Autumn.
Following the success of last
year's event at the Wembley
Conference Centre* which
attracted over 10,000 people,
iltis year’s show will be held in
the larger hall three of the
Wembley complex. This will
enable visitors to be admitted
more easily and help avoid the
queueing problems which
resulted from Wembley safety
regulations last year.
The show dates are Friday
October 36 to Sunday October
IK 1902* although the organ-
isers* Safe sell Exhibitions* are
also keeping options open on
an extra day {possibly Thurs-
day October 1 5) fur a special
educational preview.
Discussions are taking place
with Acorn Computers conc-
erning the company’s involve-
mc rti with t he show * W i t h
Autumn being a key lime for
new products, it is likely that
the company will once again
use the show as a Latinchpad.
Meanwhile, a large number
of exhibitors from the Acorn
marketplace have already
booked space and early indi-
cations are that the show will
be bigger and better than ever
Watch BAU for more details
in the near future - meanwhile,
make a note in your diary for

stand space should be directed

DIRECT COLOUR FOR THE ARC
The BJC300 used in the Colour Direct package from Computer Concepts
AFTER the success of the
Arehi medes-dedi cated Laser-
Direct printer range. Computer
Concepts has turned its atten-
tion to the colour printing
market. The result is
Colon rDi reel* a 24-bit colour
printing package based around
Canon*, s brand-new BICBQU
colour ink-jet printer. The
RJC800 is a 360dpi (dots per
inch) printer and* unlike some
of the cheaper alternatives, the
Canon is said to prim true
blacks resulting in superior
contrast. Colou rDi reel print-
outs seen by BAU were cer-
tainly impressive. Another
advantage of the BJC80D is
that it can print up to A3,
Rise OS only handles eight-
bit colour palettes at present,
which limits printed results to
256 colours, even though the
Archimedes has a selection of
4096 colours, However, Com-
puter Concepts’ printer driver
is 24-hit colour capable, to
match i lie ability of the printer.
This provision also anticipates
future Archimedes video chip
developments. CC also claims
its printer driver code, which
addresses the parallel port
directly* is extremely fast and
can work in the background.
Computer Concepts sees
Co I our Direct as a perfect
match for the new ArrW&rks
package, as well os for existing
Impression users. Colour-
Direct is due shortly and has a
recommended price of £1995
plus vat. At a later date, com-
puter Concepts plans to sell
the printer driver separately.

• THREE Acorn AS000 compu-
ters are at the heart of a new in-
store broadcasting system being
used by Asda supermarkets The
superstore chain has set up its
own AsdaFM radio station which
broadcasts to its 150 outlets via
the Astra TV satellite. The three
ASOODs control scheduling opera-

work) telephone line, which
distributes signals to the satellite
uploader. The system is provided
by Norsat International sub-

European director, Tom Wood-
ford, explained that ASOOOs were
chosen because of their network-
ing and multitasking abilities -
which means anyone machine
could take over the functions of
another, guaranteeing reliability.
Archimedes are now controlling
operations at four other indepen-
dent local radio stations -two m
the UK and two in Malaysia.

IDEAS FROM ANOTHER WORLD
The Logitech Fotoman - digital image capture on the Archimedes
KEEP Lin eye on the IBM PC-
compatible market and. when
a good idea comes along*
make it work on the Archi-
medes. Thai is the strategy
adopted by DT Software*
which this month launches
several new products.
First is a Floptical 21Mb
floppy disc drive. This is a
conventional looking 3,51n
drive which has ultra- thin
magnetic data tracks enabling
a much greater recording den-
sity. Instead of the normal 1 35
tracks per inch dpi > density.
Floptical packs have over
KXXltpi. A liny LED optical
sensor is used to guide the
heads along laser etched
grooves. It remains compatible
with all existing 3, Sin floppy
disc media.
The Floptical drive is a
SCSI device and DTS provides
the necessary software for
operation in the Archimedes
environment. The drive is pri-
ced at £399*95 plus vat and
blank 21Mb discs will cost
around £15 each.
Another new peripheral
from DTS is Logitech’s Folo-
man camera. This is a black
and white solid state camera
which stores up to 32 pictures
digitally in on-board Ram. Pic-
tures are then downloaded to
your machine via the serial
port. DTS already sells an
Archimedes camera system
based around the Canon Ion
still-video camera. This system
is colour whereas Fotoman is
strictly monochrome, but the
theory goes that Fotoman
images will be considerably
sharper, and of higher resolu-
tion because die image data is
first-generation*
By comparison, analogue
st ill- video images must first be
digitised* a process which
introduces a certain amount of
distortion, and the luxury of
colour must be paid for in
lower resolution* The Fotoman
camera can also lake standard
video camcorder lens attach-
ments. An Arc Fotoman
system is £55 3.1 5 plus vat.
Finally, DTS has a new
range of budged mu I ti scan
monitors sourced from Japan.
The range is made up of 14.
15* 17 and 21 in displays. DTS
points out that its monitors
operate a scanning range of
1 5-38 KHz, ideal for Archi-
medes screen modes, including
modes 12 and 15. Other multi-
scan monitors often scan
between 30-65KHz, which is
not suitable for lower re solu-
tion screen modes.
The l Sin and larger models
also sport a four-setting video
pre-set to minimise the need 10
constantly re adjust the screen
position when changing
between certain screen modes.
Prices are: Min* £297.82;
I Sin, £485: I 7im £680*80; and

expert. Chris Honey.
Apart from sharing the goal
of providing a full -speed
hardware-based PC environ-
ment on the Are, it is interest-
ing to note that the two
competing designs differ in
more than just minor details.
The Watford card will feature
a 25 MHz AMD 386SX PC
chip, claimed to be 25 percent
faster than the 20MH/. Intel
386SX processor used by
Aleph One. While Aleph One
decided to interface its card
with Acorn's new PC Emula-
tor, Watford Electronics has
chosen to design what is effec-
tively a stand-alone PC which
can live inside the Are hi -

ford's card could have an
optional keyboard and monitor
attached to it and two people
could use a single machine at

Chris Honey says his design
route avoids the display limita-
tions of the PC Emulator,
which can only partially emu-
late a full VGA screen. The

NEWS IN BRIEF
• THERE have been some
changes in Acorn 1 s marketing
personnel line up. Most notable
is the arrival of new education
marketing manager, Peter Talbot,
from Commodore (see education
column page 13). Simon Wood-
ward takes on some of departing
Warwick Hirst s former respon-
sibilities for valued added
solutions, within a new profes-
sional solutions operation,
covering initiatives such the Pro-
fessional DTP package.
Consumer division manager
Bob Coates takes on wider
responsibilities as general mana-
ger of consumer and interna-
tional markets. Corporate affairs
manager. Brian Salter, also gets
more responsibilities and is now
head of publications and events
organisation.
The reshuffle took place after
the Computer Shopper Show last
December, which was not
regarded as a success for Acorn.
Although it had a presence at the
show, Acorn's stand space was
booked late and there was no
time to capitalise on its presence.
• CRADDOCK Computer
Systems (CCS) has revealed that
it is designing a modular memory
upgrade system which will
enable ASOOO users to plug in a
total of 16Mb of Ram. The
upgrade features a motherboard
which brings total memory up to
3Mb. This involves de-soldering
the ASOOOs surface-mount
Memcla controller chip, which is
why CCS carries out this part of
the fitting. Extra 4Mb upgrades,
giving a potential maximum of
16Mb. are provided in the form
of small daughter cards' which
plug into the motherboard. Con-

• HEWLETT-PACKARD has
introduced a double capacity ink-
jet cartridge for its Deskjet range
of printers. The old version used
a sponge to attract the ink to the
business end of the cartridge. Ink
reservoir space has been saved
by eliminating the sponge and
the cartridge case is now trans-
parent so you can see clearly
when the ink is getting low. The
new cartridge has a typical life of
about 1.000 A4 sheets. The cartri-
dge is priced at £21 plus VAT.
10 BBC ACORN USER APRIL 1992
Last week. Miss Brown was in a tangle. Her music class wasn’t prepared
in time. One group wanted to play the drums, but the music budget barely
stretches to a tambourine. Another wanted to write its own music, but it
all got rather messy. In the end, she got them all to sing a round song.
This week. Miss Brown is using Notate. Now composing music is easy
— notes, rests etc. can be placed directly on the screen. Then the music
can be played back immediately, and changes made to rhythm, tempo or
pitch. When it’s done, they’re going to print out their piece — a nice neat
copy for every musician in the class.
Next week Miss Brown is going to introduce "Music of the World'.
African rhythms, marches, rap, pentatonic scales — Notate can do the
lot. It's even simple to move individual parts between tunes — ever
heard the National anthem with a reggae percussion section?
Notate uses the standard Archimedes ‘ voices". The computer can sound
like anything from a cow bell to a trombone, from a melodic tom-tom to
a hand clap. And up to eight of these Instruments" can be played at once.
Miss Brown has a sound sampler attached to her Archimedes too, so she
can record more of her own instruments. Including the human voice. So
now three students are singing a barber shop quartet — the computer is
humming the fourth pan.
Whether you want to play percussion with seven year olds or think theory
with seventeen year olds.
Notate offers the following features:
♦ Comprehensive support materials
in the manual and on disk
♦ Up to eight individual staves
♦ A wide range of synthesised and
sampled sounds
♦ Ability to use accidentals and
repeats
♦ Full range of lime and key
signatures with control over tempo
and volume
♦ Automatic checking of note length
relative to the bai space remaining
♦ Easy^o-use rape recorder style
control panel
♦ Chod facility
♦ Mixer controls to adjust stereo
balance and volume of all tracks
♦ Configurable for different levels of
musical skill
♦ Editing facil tries which , like word
processing, include cot, copy,
move and delete within bars,
staves or between compositions
♦ Up to four compositions editable
simultaneously
♦ Ability to transpose single parts or
whole compositions
♦ Export and import of MIDI format
I files
♦ Abiliry to play via M I DI where a
suitable interface is fitted.
Notate is available now,
priced at £59;
A site licence for Notate
costs £190 for a primary
school and £330 for a
secondary school

NEWS IN BRIEF
• ACCORDING to a retent edi-
tion of Private Eye, junior
education minister Tim Eggar
caused some embarrassed gig-
gles when he opened the SETT
Show recently. During his tour he
was introduced to Acorn's
managing director Sam Wau-
chope and r considerably
Impressed by the power of the
Acorn machines, suggested that
it might be a good idea if they
were, er r used in our schools.
After a short silence, Eggar's
guide informed him of Acorn's
contribution to educational hard-
ware (found in 35 percent of
schools) before moving the min-
ister on.
• MEANWHILE, as revealed in
our news pages this month.
Acorn has finally appointed ex*
Commodcre man, Peter Talbot,
as the new manager of its edu-
cation division. Talbot; 33, was
national sales manager respon-
sible for government and
education business at Com-
modore Business Machines. A
former teacher, he also spent a
couple of years running Granada
Business Centres in London.
Acorn's sales and marketing
director, Mike Q'Riordan, said:
'With Peter's combination of
experience of the education mar-
ket, and of sales and marketing, 1
am sure he will bring to Acorn a
wealth of benefits that will help
us to continue our leading role
within the education sector.'
• A MAJOR step forward in
examination administration by
schools has been developed
using the Archimedes. Over 45Q
schools wiil be involved in the
project for the submission of
exam entries, managed by the
University of Cambridge Local
Examination Syndicate and
Campus 2000, supplier of elec-
tronic information services to
education. Most of the 'spade
work' for the project was carried
out on the Archimedes. The soft-
ware was then ported over to
PCs, on which the system will
run, although there is the pos-
sibility of linking into the UCLES
project with an Archimedes
machine. Campus 2000 is jointly
operated by BT and Times Net-
work Systems, tel: 071-732 7143.

FaxPack is a fax expansion board for the Archimedes
range of computers allowing your computer to take on
the job of a conventional fax machine hut with the
benefits of being fully integrated into the Archimedes.
FaxPack offers full background send and receive
capability. You can send a fax simply by selecting the
PRINT option from any RISC OS application, with
control returned in just a few seconds. Fax Pack then
proceeds to diat and send the fax while you carry on
using the computer.
Receiving faxes is also completely automatic. FaxPack
will answer the phone and store the fax away on your
disc while you continue to use the computer. Once
received the fax can be viewed on screen fusing a
special anti-aliased display to improve on-screen
readability] and printed. Any portion of the fax image
can be saved as a conventional sprite. Alternatively
FaxPack can be made to automatically print on receipt
of a fax. which with a LaserDirect printer, is completely
automatic and in the background.
There ere numerous advantages of a computer based
fax system over a conventional machine:
□ Very high quality, pixel perfect faxes - try sending a
fax of 8pt text from a conventional fax machine !
J Since there is no need to print then re-scan a
document, FaxPack saves time, paper a nd money when
sending faxes.
j Rather than junk fax mail wasting your costly fax
paper, youcandecide to delete unwanted fax files
before printing.
—I By receiving and sending from the computer
FaxPack offers a higher level of security than most
conventional fax machines.
J Fa x Pa c k a 1 1 o ws e I e ctronic arch iving of fax
messages and is one step towards the truly paperless
office,
J FaxPack usesyourstandardArchimedesprinter
and so can print on plain paper rather than thermal
paper,
in addition FaxPack can be used as a data modem, to
send and receive any Archimedes file or directory of
files to other machines fitted with FaxPack. Because of
the 9600 baud rate of fax systems and the use of data
compression FaxPack is faster than practically all
conventional data modems and permits background
data transfer.

NEWS IN BRIEF
WHOSE LINE IS IT ANYWAY?
HOW many readers skip over
the com ms column, thinking
that it's loo complex for them.
Maybe they have watched the
Him Wargames and imagine a
whole sub-culture of boffins,
hacking their way into hidden
computer networks.
Well, nowadays its not
quite like that. Com ms come
into many aspects of life, from
the cashpoint machine to ord-
ering in a high street book-
store. At the home computer
level, playing online games is
a favourite corn ms pastime.
So, if you arc a computer
novice, how do you get
started? Well all you need is a
modem, a computer and some
suitable com ms software. A
modem is simply the box
which plugs into your phone
line and your computer. It
converts your data into strange
noises, sends them down the
phone line into a modem at the
other end, which then converts
the strange noises back into
computer data.
The cornms software is sim-
ply a package that lets you
choose the data to convert into
strange noises, and send them
whizzing down the phone line.
You can pick tip a modem for
as little as £50 nowadays and
the comins software will cost
about the same. To get started,
you don't need to worry about
speed and all that stuff - most
systems that you dial up will
adjust thdr speed to suit your
modem. The only thing to
remember is that the faster
your modem, the cheaper your
phone bill will be.
Comms software can often
be bought at the same time as
your modem but be warned -
there arc alot to choose from.
We will be looking at some
over the coming months, to
make your choice simpler.
ARCADE IN ACTION
FOR a newcomer, one of the
best bulletin boards around has
got to be Arcade. Based in
Croydon, Arcade is probably
the definitive' bulletin board
for the Archimedes, and con-
tains many celebrity names in
the user log. including support
from Acorn themselves via a
comprehensive Acorn Support
area and by a number of Acorn
staff who log on regularly, if
there is any new PD soil ware
or updates to existing soft-
ware, yon can generally lie
sure that it will go up on
Arcade first.
The latest area on Arcade is
Virus watch This is a special
area containing all the latest
virus killers together with a
run down of which viruses
each will kill and any relevant
information to help keep your
discs virus free.
If you're not on Acorn’s
mailing list. Arcade can also
provide any new Acorn press
releases, often before the
magazines pick them up. A
special download section con-
tains text-only files of news
stories updated the day they
are released.
Arcade is run on a very
friendly, dub- 1 ike basis and
u set's are always ready to help
out newcomers, or anyone
having problems with their
systein. In fact, every so often
a number of users meet up for
a drink, usually around the
London area. Arcade arc
found on OS I -654 22 1 2 or
081-655 4412. Set your soft-
ware to SN I, ANSI.
OUT AND
ABOUT
ONE bulletin board that has
come to our attention has some
rather unusual concerns.
Word smith BB is designed to
appeal to any scribes and other
creative folk out there It
seems to be the UK home of
writers and photographers and
offers many bulletins and
forums for budding writers to
share ideas and comments.
The sysop is Marcus Harri-
son. and to contact Words-
miths, set your software to
8NI and call 071-603 2302
A completely new BB to try
is available on (0795) 471515.
Called Pettetis Paradise, it is
based in Sillingboume and run
by Graham Pellet l. According
to Graham, there's lots of mes-
sages. lots of games, lots of
files and lots of fun! It also
supports Fidonet and World-
net. running at all speeds from
300 baud right up to 14 4k
baud. However, this BB is cur-
rently only available from
1 0.00pm to 7.30pm.
The Blackcat BBs, based in
Penarth, South Wales is
another new BBS to come to
our attention. Running at all
speeds from V2I up to V42bis
and boasting 300Mbytes of
online storage it caters for
most machine types. II you
know of any bulletin boards
that you feel deserve our atten-
tion. please drop us a line!

could send Janet mail, via a bul-
letin board system? Well now
you can. Sysop Edward Hobson

set up Janet E-Mail facilities on
his board so that you can send
messages to friends in universi-
ties around the country. The
Powerhouse is on (0829) 782676.

the system will start at the
beginning of March and allow
access to over 20 countries,
including the U5A, Japan and
most of Europe. For more infor-
mation, call freephone customer
helpline on (0800) 282444.
• Some A500Q users may be
experiencing problems when
using older style modems. This is
because the serial port on the
A 5000 cannot support split baud
rates such as 1200/75, If you
want to log on to bulletin boards
at this speed, you will need to
upgrade to one that will buffer
the computer speed for you.
• Ever wanted to run a bulletin
board on your Arc but couldn't
afford the cost of the software?
Carl Declerck has developed the
first public domain host system
for Arc users. More details in a
future column but meanwhile

DESKTOP
EXPLAN'S Arvo! graphics
package has recently under-
gone u number of changes.
The most important one is the
ability to work in any 256
colour mode supported by the
Archimedes. Up until now, it
only worked in Mode 13 and it
was restricted by the rather
chunky 320x256 graphics.
The new Arvo! Desktop
installs itself on the menu bar
like other Rise OS appli-
cations, hut switches to lull
screen when ran. A number of
new tools have been added and
existing ones upgraded and
refined. The price is £50 for
i he single user version and
£250 for a site license.
Upgrading from the old ver-
sion of Arvo! to Arvo! Desktop
will cost £6.50. (AH prices

RAY TRACING is becoming
increasingly popular among
Archimedes users, and many
programs are being converted
to the 32 ‘bit format. Most of
the best ray tracers are in fact
in the public domain, a source
of quality programs which is
often overlooked by the aver-
age computer owner.
QRT (Quick Ray Timer)
has been around for some time
now and has been responsible
for many of the demos circu-
lating on bulletin boards and
PD libraries. It is fully Rise
OS compatible and runs on the
desktop alongside other appli-
cations. Pictures are created by
describing scenes in special
script files, in a similar way to
the origin ei I Render Bender
program by Clares.
Output can be in any mode,
as a sprite, or as a siruight-lor-
ward 24- bit clear II le which
can be displayed to full effect

the end of March 92.
This is a presentation pEiek-
age of the same ilk as Type -
Studio reviewed 3;ist month.
Midnight Express will allow
text to be placed in envelopes
or around curves, but remain
editable. Arm code has been
used throughout, and the pack-
age is said to be virtually
instantaneous in operation.
Predefined palettes are used
for colour adjustment, remov-
ing the need to fiddle around
with colour sliders, as in
Draw. Preset envelopes are
also defined and they can be
plEieed on the page for editing,
A potentially impressive
feature is the Eibility to tile or
scale any sprite within an
object, allowing complex

Oak Solutions SCSI
First for Quality
First for Performance
and now
First for Price too!
When we launched the Oak 16 Bit SCSI card and a range of hard disc drives in 1909, they quickly became
the market leader. As with all our products, they were manufactured under a 'Zero Defect 1 quality control
regime and enjoyed an enviable reputation for both quality and reliability.
Now we have turned our attention to the COST of our products so that they continue to be the best ail
round value for money. Our new pricing structure has been made posable by our bulk buying power and
our recent move to much larger premises to keep pace with the demand for all our SCSI products.
Not only have we addressed the question of price but we have taken steps to enhance our reputation for
quality and reliability by introducing the Quantum hard disc mechanism and the low noise Papst fan into
our lew cost Worm Winnie Range of hard disc drives.
With several newcomers to the hard disc marketplace, the issue of performance has become a little clouded
of la it-, so to set things straight . we offer the assurance that size for size, you cannot buy a faster hard disc
drive system from any other manufacturer.
Oak SCSI software is Atom compatible, and allows ha rd discs to be partitioned into several logical
partitions, which may be write protected if required. This feature can prove invaluable in the classroom
situation where applications can be stored on a write protected partition - safe from accidental or malicious
tinkering - whilst still allowing a read/write partition for data and scrap iiles.
Every Oak Solutions hard disc comes complete with over 1250 worth of FREE software: the original Genesis
hypermedia software. Disc Tree hard disc management software which allows easy backup of your drive to
floppy disc, Euclid, the de facto standard for Archimedes 3D software, RISC OS Companion, Remote Logon,
and tlie addictive Worm Battle tank game.
For professional security 7 of data under RISC OS. our tape systems provide an unrivalled solution to your
backup problems for any type of hard disc or network file server.
All our tape backup systems include DakTape. a comprehensive and widely acclaimed RISC OS backup
software program. Backups are done on a tile by file basis with versatile control over backup criteria.
Automatic backups may be triggered at pre-detemtined times, and printouts of tape contents can be
automatically generated. Restoring from tape is simple and intuitive Files and directories can simply be
dragged from a tree viewer or directory viewers, either to disc, network or even directly into an application!

STAR LETTER £15
I would like Is* make a sug yes-
lion u> all hardware and
software publishers. I have
used a variety of Acorn com-
puters, from Ehe Electron,
through the Model B and Mas*
ter to the BBC’ A3000. Overall
I have found that Acorn has
been pretty good in its docu-
mental ion. as have most third
parties. My suggestion is not
about the actual text, but the
way it is presented.
Ei seems that there is no
standard style in which infor-
mation is published. Also
some software is published in
card board ‘books' which fall
apart easily and in thin card-
board boxes which have no
strength at all. leading to a
messy shell.
It appears that a lot of
Acorn-related merchandise is
purchased though mail order,
so eye-catching packaging is
not really necessary. Why not
adopt the simple idea that
many computer companies
have of using a loose-leaf
hinder? Compute r Concept s
DTP package. Impression,
uses one. Any upgrades to
software would only need a
few pages, or a file for prim-
ing, rather than a new book, or
some hastily printed sheets.
Since most DTP software
supports various page sizes
and formats, it is quite feasible
that Public Domain and less
expensive software instruc-
tions can be provided as test
files, which could be primed
out if desired. Already a lot of
PD software is only docu-
mented on disc.
While such a system may
not he immediately imple-
mented, I hope publishers
think about what they are
producing.

As suggested in the article

92 i, a quick way to update the
modules in the System direc-
tory in the absence of Svs-
merge is to select Full Info
from the directory viewer and
look at (lie dale stamps of each
module. But this method can
be hit-and-miss if someone has
re -stamped the file with a dif-
ferent date to that of the
version date of the module, as
I have found out the hard way,
I believe Sys merge also looks
at i lie dale stamps - if this is
so. I hen surely it must he used
with caution?
The only way to ensure you
have the latest modules is to
load each one and type *Hdp
Modules from the command
line, and then have a look at
the version number and date. I
keep a text lllc called Versions

SECONDHAND HAPPY
1 have a BBC A3(XH> with
monitor and 2\1h of memory
which I bought along with a
monitor stand for £400.
Although ii was secondhand,
it hasn't given me any prob-
lems so far.
On the other hand my friend
bought an Amiga 500 base
unit with a hit of bundled soft-
ware and 5I2K of memory for
the same price. He then spent
another £250 on a monitor and
another £65 on a second drive
- most of his games were
unplayable without one. He
would buy a printer, bui is
seated that ii would be incom-
patible with his software.
So* the Amiga is great for
games, but most of them come
on two or more discs, take a
long lime to load and hog the
whole machine. Archimedes
games are usually fast load-
ing. are desktop friendly in the
main (sometimes even multi-
tasking] and disc sw aps can be
kept to a minimum.
Looking at the graphics side
of the Amiga, you do have a
lot of colours, but these are
only used in ray tracing. Inci-
dentally. lias anyone ever
heard of outline fonts, or an
easy -access version of Baste
for the Amiga?
The arguments for the Arc
are numerous. I would urge
anybody thinking of buying a
brand new Amiga to check out
the secondhand Arc market
before they part with their val-
uable cash,

PRESSING ERROR
I would like to raise a point
regarding the review of ArcFS
and Spark ( BAU February).
This review gives the impres-
sion that Spark and ArcFS are
public domain programs, or
perhaps Shareware. They arc
not and I would not wish
anybody to gain the idea that
they are.
At the end of the review,
while the correct information
is given about Compression.
for AnFS it is simply stated
dial 'ArcFS... is available from
most public domain libraries'.
As for Spark, there is just the
statement: Anyone who uses
bulletin boards or obtains soft-
ware from PD libraries is
probably familiar with an
application called Spark*.
Spark and ArcFS are not
Shareware. They are available

□ Paul Sand ford of Shef-
field wants to extend his
knowledge of assembly langu-
age programming on his BBC
B computer,
Having read Joe Telford's
BBC Micro Advanced Pro-
crammings which covers many
programming techniques not
explained in the user guide, he
would now like a more
advanced book that covers
topics such as interrupt han-
dling and writing faster games
in machine code,
Q There are a number of
good books available for
the BBC' computer, although
you could find that many
dealers don't hold much
stuck now, so you may have
to hunt around. One to keep
a look out tor is Cracking the
Code by Benni Notarinmii, It
is puli I is lied by Pan ( ISBN
0-330-28666-8} and explains
many programming prob-
lems such as animated
graphics, interrupts, writing
maths routines in machine
code and how to start writ-
ing games. It is aimed at the
slightly more competent
programmer, ah hough docs
provide an easy to under-
stand introduction to assem-
bly code programming.
□ A common problem,
aired by R Kendall of
London is that of saving
machine code programs so that
they reload and execute at a
specific memory location. He
asks if there is a way of saving
a portion of memory so that it
loads at &900 automatical I y
when you reload it.
Q The answer to this
question depends upon
the syntax of the keyword
•SAVE when you originally
save the object code. Firstly,
ensure that you compile
your code to assemble at the
address you want it io reload
it. For example, to get your
code to load at &9G0 t set P%
to &9IID us you compile it
and then use the command
•SAVE pniK UDA A (Ml 90 A which
will save the portion of
memory between 900 and
A(H). setting the execution
address to &90A, When you
load and run the program by

□ Teacher. Susan Chapman
from the Netherlands is
trying to computerise her
school library recoids using an
Archimedes computer. She
wonders if there is any suit-
able database software that
will allow her to keep book
titles, authors, classification
numbers and topics, and to
update them as required.
Another primary consideration
is easy use by young children.
□ There arc a growing
number of databases
available for the Archimedes
range of computers, ranging
from traditional style data-
bases which consist of many
‘record card' type entries to
the more recent 'multi-
media' style of database
where the entry data can be
of a variety of formats
including pictures and data
from other applications. For
your type of use I would
recommend Flexijite by
Minerva Software, (0392)
437756. w hich is reasonably
easy to set up for the data
you require. Once set up.
young children and old can
interrogate the data by using
simple icons for forward,
backwards and search com-
mands. simitar to those on a
video recorder.
For more advanced use it
will also allow y ou to create
reports and search for
entries when you do not
know the exact spelling.
□
Problems are often
encountered using the
outline font system on the
Archimedes, David Cooper of
Glasgow asks if there is any
way to load text into Dmir
with the aim of printing it out
using a printer driver.
He repeatedly gets two error
messages - either. Text area
must end with a newline
character* or. Warning: text
area font Trinity, Medium
could not be loaded 4 .
□ The first error is rea-
sonably easy to rectify
and is usually caused by
using Edit to compose the
original text. When you fin-
ish typing your text in.
remember lu press RETURN
at the end of tlu document,
thus leaving a blank line at
the bottom. When you subse-
quently load your saved text
back into /hw, it will then
know where the bottom of
the text is.
The second error is caused
by Draw not being able lo
find your fonts directory.
Draw looks for Trin-
ity .Medium by default so you
should double click on Fonts,
before you load Draw.
□ A quick question next
from Freddy Hutton of
Oxon. He is currently using
Maestro in order to compose
music on his Archimedes
A4IQ/I bill wants lo produce
a hard copy of his composition
on a printer. He asks if there
is an application to enable him
to do this.
Q Vour best option here is
to upgrade to Rhapsody
by Clares Micro Supplies,
(0606) 48511. which is basi-
cally an enhanced version of
Maestro. As such it will load
your existing Maestro tunes
and convert them to the new
Rhapsody format. It not only
contains support for Rise
OS printer drivers, enabling
you to print out your fin-
ished tune, but also has a
host of additional features
not supported by Maestro,
For a professional output
you can get an additional
package called Sen redraw
which will produce printed
results just like genuine
manuscript shed music.

chased ait ATPL sideways

unfortunately he didn't get

them both into the corre-

remove the power connectors
adjacent to IC32, bend them
at 90 degrees and replace
them. Next, remove the
shorting link from the lower
half of S21 and connect Ihc
two flying leads from the

One often voiced ques-
tion concerns recovery of
deleted files on Rise OS discs.
Mr G Sheridan of Bedford-
shire echos many peoples*
thoughts when he admits to
accidentally deleting some
files from his discs. Me wants
to know if there is any way of
retrieving the lost data,
□ Restoring deleted data

enced of users, so I would

and floppy discs and sup-
ports any filing system.
David Hart burn of Tyne
& Wear has a problem
his Archimedes internal
dock He finds that it often
forgets the time, despite
resetting the machine and
using Alarm to set the clock.
Q This sounds like a
symptom of a flat bat-
tery inside the computer.
Have you noticed any of the
□
with
G
computers' other settings
becoming corrupted or
changed? It is a good policy
to replace the Chios Ram
battery every year* as a
weak battery cats quite often
give confusing or unpredict-
able results during use of
your computer* If replacing
the battery does not cure the
fault, it is possible that you
have a faulty clock chip
inside the machine, which
will need checking Ivy an offi-
cial dealer.
m
Another Archimedes disc
error is often encountered
by M Donkin of Lincoln, He
reports getting a 'Filecore in
Use' error from time to time
when using a lot of discs such
as DTP, Font and work discs.
He asks if there is a simple
solution to avoid this,
E ! Every time you click on
a new disc, its name is
added to a list of disc names
currently held inside the
computer. This is kept until
you either turn off the
machine or dismount the
disc. Unfortunately, Rise OS
has a limit* beyond which Ihc
* Filecore in Use* error is gen-
erated, The easiest way to
avoid this is to dismount
discs as you finish using
them, just click the middle
mouse button on the disc
icon and select the
‘dismount' option. It is good
practice to remember this
and also ensures that you
don’t have too many filer
windows open on the screen,

Quality Disc Drives from
Watford
AH our Disc Drives are Double Sided and will
operate in both Single and Double Density modes.
Afl 5,25' Disc Drives are 40/80 track switchable.
For ease of use, the switches are front mounted.
Various UK * manufacturers " of disc drives for the
BBC Micro (more accurately , "packagers* labef
other manufacturers drives with their own name).
We buy the high quality NEC and Mitsubishi drives
in targe quantities d/rectly from the manufacturers,
package them and sell them at "deaier" prices
direct lo the public.
if you look around the popular BBC Micro press,
you wili find that the prices wo quote for the top
quality, new slimline disc drives are , virtually
wilhout exception, the best around. These prices,
coupled with the backup of one of the country's
largest distributors of BBC peripherals provides a
superb deal.
Unless you anticipate using dual drives in a futiy
expanded BBC system for tong periods of time with
tittle ventilation, then we suggest that our range of
“CL” disc drives without the PSU (Power Supply
Unit) would be quite adequate (extensive tests
within our workshops have confirmed this). AS I
drives are supplied complete with a SPECIAL
UTILITIES Disc, Cables and Plugs. The Drives
with power supply have a mains moulded plug for
safely purposes, f deaf for Schools £ Cottages.
When using a BBC Micro, most people find
themselves short of desk space. The Watford's
BBC Micro plinths form an ideal way of recovering
some of this precious space. Your BBC Disc Drive
and Monitor can ait occupy the same vertical
footprint and still be comfortably situated, With She
Watford Double Plinth, your Disc Drive is mounted
vertically at one side, leaving a very valuable area
directly in front of you for such useful items as
spare discs, pen. paper, reference manuals., etc.
Follow the trend with a Watford pfinth. (Turn to the
6th page of our advert for the Plinths).
P.S, AH our 5.25" Disc Drives with PSU are
compatible with the Compact Micro. Alt you require
is our special Compact Disc Drive cables designed
by us.

Revealed Handbook
So you bought yourself a new printer,
because the salesman in the shop
showed you how qlever it is and
impressed you with all sorts of
printouts to show its capabilities - be
may even have offered you a special
price.
However, now that you have got it
home and connected it to your BBG
microcomputer, you are wondering
how to make it perform these magical
tasks. The manual seems to give no
ciues, and when you type in the
example programs, the computer
throws the LPRINT statements back in
your face.
Now what do you do, when this £400
piece of high technology refuses even
to move its head, and you have stayed
up until 2 in the morning with copious
supplies of coffee, desperately trying to
print something out? Once again,
Watford Electronics comes to your help
with our new book entitled 'THE
EPSON FX-KAGA PRINTER
COMMANDS REVEALED’.
This book describes in plain, easy to
understand English, how to use and
make the most of your KP810.
PWHD80A or any other Epson FX80
compatible printers tike Panasonic KX-
P 1080/1, etc,, with the BBC Micro,
both from Basic and Wordwise.

maximum in graphics capability from
your printer and includes full indexes
allowing you to cross Index the
numerous commands. Every
command is explained in detail, with
an accompanying BBC Basic program
and an example of its use from
Wordwise.

Stop the Confusion!
Do you have to use both Acorn
computers and PC's? Would you like
to use your Archimedes or A3QOQ in
PC-emulation mode but are unsure of
the new commands?
Although Acorn machines (such as the
BBC 8, the Master, the Archimedes
and the BBC A30DO) are mainly used
in education, most commercial
computers use other operating
systems, particularly MS-DOS. As a
result school computer users are at a
disadvantage whan moving inio
'business' computing . PCs and other
commercial computers use MS-DOS
as the operating system, so
commands tor formatting, copying,
backing up, priming and the modem
are not Ihe same. Even file names are

In the first of a
two-part series on
special needs,
CHRIS DRAGE
looks at some
hardware options
WITHIN REACH
Q he hardware options for special needs com-
puting have been growing steadily in recent
year. This is especially true for Ehc RiscOS
machines which, unlit recently, were over-
shadowed by the Beeb.
Acorn has now put together a BBC A30G0
Special Access System (see above) in two
guises: the first includes the computer, a serial
upgrade, Morley Electronics' User/ Analogue
card and seven utility programs; the second also
includes a monitor and Pres monitor stand.
The upgrades allow access to overlay key-
boards, touch screens, modems and switches,
but it is the utilities provided which are at the
heart of the package. One of the utilities pro-
vided is ASP, switch interface software which
allows disabled users to access Rise OS appli-
cations, by using a single switch device.
The others included are: Special KB which
allows the numeric keypad to emulate mouse
functions with a very useful 'sticky keys* option
to emulate multiple key presses. Big Fir offers an
enlarged and visible pointer whereas Close up
presents a small magnified window which can
move around the screen. Flasher gives a more
visible flashing caret and a cursor-homing
device. With Chars, typing can be achieved,
using the mouse to select characters from a
screen display. Bigscreen (Mode 36 & 37) and
Screen V (Mode 43) are both large screen modes
to display text, icons and menus in larger sizes.
The Acorn package also allows you to use Midi
(musical instrument digital interface) equipment.
There are many other interfaces and upgrades
that can be used to connect up external devices
(the Morley Electronics User/ Analogue podule
is good value for money) but Access 1000 from
Hybrid Technology enables overlay keyboards,
touch windows, joysticks, switch units and the
company's Air Recorder to be connected to a
BBC A 3(X)U/ Archimedes computer without
using the standard podule user port.
Indeed, the Access 1000 combines the func-
tions of the user poit and a switch access box
forming the basis of Hybrid’s Access Link,
which permits add-ons to be daisy-chained on to
the computer’s printer port, These avoids the
need for the serial port upgrade so leaving it free
for other add-ons. The interface has four jack
sockets designed to take switches and a familiar
BBC-sly le user port connector and also provides
a small through -connector with the printer
connected at the end of the queue.

Northwest SE MERCs Overlay Keyboard
Keyboard is the mainstay, with over 1 20 overlay
keyboard programs. The overlay keyboard is
extremely versatile, since it is simply a piece of
paper. Basically, it provides a choice of icons
which the user presses instead of the normal
keys. They consist of 128 programmable cells,
but you don’t need to know that since you
usually only load a program and use it. Concept
Designer and Conform make programming the
device easy, if you want to create overlays for a
specific purpose. Touch Explorer Plus, Folio,
Concept Kids are also impressive programs.
The Overlay Keyboard is made from high-
impact plastic, which makes it both light and
sturdy, meeting educational safety and design
criteria extremely well. It works with the BBC
B/\1 aster and the BBC A3000/ Archimedes if a
user port or Access 1000 is present. A single
switch interface ia built in as standard and is
used by inserting the switch jack plug into a
socket which automatically disables the key-
board and selects the switch. Most important ly.
the Overlay Keyboard is completely compatible
with all existing software.
Other input devices include touch screens (see
BA U February 92 issue), alternative keyboards,
mice, traekerballs, switches and voice input
devices. Two leading Touch Window systems
i Keyboard Technology and Lmgenuity) are
made up of the same hardware, with differing
software drivers. They are accurate, responsive
and can be adapted to fit almost any monitor.
Their high resolution, coupled wiih the ability to
be removed from the monitor to be used as a
Tracing window", add to their versatility.
One successful alternative to the mouse is the
Deha Cat which can prove very useful in
specific circumstances, especially if the joystick
is firmly mounted and an extension tube is fitted
over I he stumpy control stick. It can offer con-
trol via foot (buttons) and mouth (stick). If you
require a better mouse than the standard one
provided with the Archimedes, then I recom-
mend Clares' rodent, which nestles comfortably
in the palm of the band, allowing the fingers to
rest more naturally over the buttons.
For a trackerball (literally an upside-down
mouse) the sturdy Marconi unit has performed
well over the years, but is shortly to be eclipsed
by the new Ark Tracker. Not only is this tracker
ball extremely rugged but it has all the mouse
operations on separate buttons. A perspex over-
lay can be added to help with locating the
buttons and a separate switch provides control
over the pointer speed. As the unit remains
stationary, pointer operation is controlled, with
the fingers alone negating the need to move the
whole arm - useful for a disabled person who
has fine motor control hut finds larger arm
movement more difficult.
For those whose only means of communi-
cation w ith a Beeb is their voice, the MicroMike
has proven successful, giving voice- volume
control over a variety of activities, Et can pro-
mote vocal play, control of volume and liming
of vocalisation. In order to use the device with
an A3(HX)/Arcbimedes. a user port must be
installed. The popular Sid and Mike wjftware has
now been converted to Archimedes use.
Alternatives to the standard keyboard are
available from Special Access Systems, starting
with a metal keyguard which fastens on to the
keyboard. Holes on the keyguard permit hands
lo rest on the guard, while fingers can access
individual key holes. The company’s Program-
mable Expanded Keyboard should also prove
valuable to those who are restricted to using a
toe. mouth stick, headpointer or a single finger.
Users can also perform multi key presses as one
operation and four programmable delays can
cope with uncertain or over- long key presses.
Furthermore, bright LEDs or programmable
sounds can help those with sensory disabilities
to know when a key has been pressed.

clip on over the existing keyboard, keeping
unused keys hidden from prying fingers and
making programs highly resistant to accidental
crashes, Obviously such a device is tied to
specific software applications and as yet. only
two models are available: the Matchbox Key-
board (for matching games) and Moneybox
Keyboard to accompany the Moneybox suite of
software. One advantage of these devices is that
they provide sensory feedback to the user.
Incidentally, the Matchmaker interface can be
used to connect virtually any input tie vice device
(switch, joystick, trackerball. overlay keyboard,
and so on.) Next month, we wilt look at the

CHANGING FACES
JAN VIBE presents a new look at animation on Acorn machines
J s there anybody who has not seen Michael
Jackson's video. Dangerous 1 } In the video
there is an fascinating sequence of faces
which change softly from one to another. This
made me wonder if it was possible to do
something similar on my trusty Acorn machine,
Well, it was, and here it is,..
The program draws a lace on the screen. Then
slowly the face undergoes a metamorphosis,
changing into another and another. It is a great
showpiece, and has an almost hypnotic effect on
people. Part of the inspiration came from an
excellent book by A Dewdney called The Arm-
chair Universe In fact, the data for the face is
based on an example w ithin the book.
THE THEORY
The program initialises by setting up two
screens, an active and a shadow screen. It then
generates two completely different faces, let's
call them face I and face! These faces are stored
as PLOT commands in arrays.
In the main loop, the co-ordinates for face]
and face 2 are being averaged by a formula
which, at the start of the loop is weighted solely
towards face] but, at the end of the loop is is
weighted solely towards face2, By using this
formula, a face which lies somewhere in
between can be generated .
This face is drawn on the shadow screen.
When the drawing is finished, the active and
shadow screens are switched, the weight is
changed a little towards face2 and the main loop
is entered again. The face is eventually changed
totally into face 2, then face 2 is made into fa cel,
a new face2 is generated and the changing
process starts again.
THE PRACTICE
To run the program, type in Face l and Fact!.
(see our yellow pages box). When you run
Facet some data wilt be created, then you can
run Face2. the main animation routine.
The program consists of three parts: an initial-
isation, a face generator and a main loop, which
makes the face slowly change from one to
another The most complex part of the program
is the procedure PROCdistan. It takes the array
distort and returns it distorted by the required
amount. Two arrays, re fx and refy, are the
coordinates for face l and face 2, The original
coordinates are not changed at all by the distor-
tion of the face and are these are therefore stored
in a single array.
The distortion method is mainly a simple
multiplication around a point. It works like this:
X _di.Ht=r X_fa£c- X _ref) ■ Z_d ist+X jet' where X_di.Hr is the
distorted x value, x_rate is the original value of
x, x_ref is the reference point and z_dis.t is the
distortion factor. The same calculation is of
course being done for Y_dist. In the procedure,
the distortion factors (lucewittih etc,..) are gener-
ated by the random number function
FNmdiminjftBKL Then the nine reference points are
read into the the arrays tlrefs and drefy.
These points arc used in combination with the
distortion factors w hen changing certain parts of
the face. The first of the reference points is a
global point, used for distorting the entire face.
Reference points two to nine also go through the
distortion calculation. Incidentally, line 1 230 in
this loop contains the calculation that makes the
face egg shaped, with the point either at the top
or the bottom.
In the main loop (1290-1650) the points of the
face are distorted. The general distortion of the
entire face is being handled by lines 1300 to
1320. This calculation is exactly the same as the
one shown in lines 1220 to 1260. Most of the
distortion of various parts of the face are made
by multiplication around a point, but some
require that the parts are moved too - such as in
the case of the eyebrows. This happens at lines
1370 and 1410 (the distance between the eyes)
and also at line 1590 (which produces the rais-
ing of the eyebrows).
The part of the face to be distorted by certain
factors is controlled by counting the points in
the face- drawing and by testing the counter.
This is what happens in the various when
blocks. When the counter has reached 1 tt6. the
face drawing is complete. The distorted face is
then stored in arrays, which takes place at lines
1630 and 1640.
EIGHT-BIT BONUS
BAU programming guru. David Lawrence has
also written a version of Face for eight-bit
owners. To use it. type in FaceJ, Face4 and
Face5 (see our yellow pages box) and then run
them in sequence, if pa<jH is greater than &ikxl
you need to lower it to this value before running.
The program works by calculating the in-
between stages (this will lake 20 or so seconds)
and then the animation takes place.
MODIFICATIONS
There are lots of ways that this program could
be extended Colour is (he obvious one. although
it might make the program too slow, Oi how
about user control to make an interactive ident-
ikit. Indeed, why stop at the face? The program
could be used on the entire human body!

THE BBC MICRO
A forthcoming BBC programme will chart the progress of home computing
omputer technology has taken a quantum
leap in the past 10 years or so and now
personal computers ean now he found in
many homes and offices. Yet in (he Late 70s this
was the faraway dream of a lew electronics
boffins. who were putting together boards and
switches on kitchen tables and calling them
'computers’, Personal computing started to gain
momentum just over a decade ago, courtesy of
the BBC's computer literacy project which set
out to explain the principles of computing to a
wider audience.
The literacy project was based around various
television programmes* the first in 3982 also
marked the television debut of the BBC micro
computer. Ami rite rest, as they say. is history...
It is that history which the BBC is celebrating
in a special 30-minme programme. The Trojan
Mouse, due to be screened on Sunday April 5
(see box for details). This programme will
examine the effects of the computer literacy
project and the BBC micro on personal comput-
ing, as well as highlight the key developments
Humble beginnings with the Acorn Atom
of the past decade. To coincide with the pro-
gramme, we have put together a special
supplement which you can find in next month’s
BBC A com User. The magazine was actually
launched in response to the success of both the
TV computer literacy programmes and the
Acorn -produced BBC micro - and we have been
around ever since, charting the ups and downs of
she Acorn market.
This month, as a Taster' to the programme,
we look back through our archives at some of
the key milestones, from the Acorn Atom right
up to the launch of the latest Archimedes
A 5000, For (he full story* be sure not to truss our
special supplement next month.
ATOMIC
Founded in 1979 by Hermann Hauser and Chris
Curry. Acorn Computers launched the System
One, followed by the Acorn Atom. Roger Wil-
son joined the company straight from university
to help design the Atom and remains with the
company today, developing new projects.
TROJAN MOUSE
The Trojan Mouse is a 30-minute
programme charting the introduc-
tion of the BBC computer literacy
project, the various series on home
computing which it launched and
the introduction of the first BBC
micro computer. Produced by Dave
Thomas, who was responsible for
producing previous computer pro-
grammes, the programme is hosted
by Ian MacNaught Davis, who
appeared in the first series.
The programme traces the
evolution of the project, the
related hardware and software
achievements, and talks to many of
the people who were involved
along the way - from Cambridge
graduates putting together the
earliest prototypes, to teachers
whose lives were completely
changed by the introduction of the
first BBC micros.
Innovators from Acorn, Includ-
ing Hermann Hauser [co-founder of
Acorn) and Roger Wilson and Steve
Furber (who helped design the first
BBC micro and later developed the
Arm chip) are interviewed. But the
programme isn't just about the
past - it brings you up to date with
current developments and poses
some questions about the future.
So be sure to tune in to Trojan
Mouse on BBC1, Sunday April 5,
10. 30am, (The programme will be
repeated on Monday April 13).

THE BRIEF
To support the computer literacy project, the
BBC was looking for a partner to produce and
market a home computer, which would be
featured in the first scries., Richard Russell at the
BBC produced a detailed specification for the
required machine. Hermann Hauser and Chris
Curry put forward the Acorn Proton design,
which was to more than match the specification.
In April 1981. Acorn was contracted to supply
12,000 machines that the BBC expected to sell
by mail order...
ONE YEAR ON
"Where do we go from here?' asked John Rad-
cliffe, executive producer of (he computer
literacy project, one year after it was launched.
The figure of I2,IH)0 machines was cautious - in
fact, more than that were ordered before the first
series was even screened.
The result? A runaway success for the BBC
and Acorn with further series in the pipeline.
Also the Micros iti Schools scheme was
launched - the brainchild of Kenneth Baker, the
education secretary at that time. The scheme
was to subsidise the purchase of BBC micros
and other approved machines,
THE ELECTRON
Chris Curry wanted to lead Acorn further into
the fast -expanding mass market for cheap com-
puters and Acorn launched the Electron in 1983.
timed for the Christmas rush and priced at C 199.
While popular, it was to be dogged by produc-
tion problems and by Christmas 1984 public
enthusiasm had waned and one-third of the
Electrons built were apparently never sold.

JUST THE BUSINESS
The Acorn Business Computer weis launched in
1984. hut it was targe and unwieldy and never
recouped the huge resources expended on its
development.
The BBC Master-driven Domesday machine
Following a disastrous Christmas 1984 sales
period* newspaper articles* particularly in The
Sunday Times, suggested all was not well with
the company.
The share price fell and finally the Italian
computer giant, Olivetti, stepped in to save the
company. Curry and Hauser signed away their
controlling interests to Olivetti, but both stayed
on ns board directors.
MASTER STROKE
Launched in 1986, the Master series seemed to
some observers as an anomaly. It was refine-
ment of the original BBC micro at a time when
there was a mass migration, by other cheap
computers, to the 16-hit, MS-Dos standard of
the successful IBM PC.
While cheaper to manufacture, the Master was
more expensive to buy and. outside the Acorn
education stronghold, it dad not achieve the
same level of sales as the original BBC micro.
The Master Compact followed, but offered little
that was new. except that it was packaged in
three boxes rather than the customary two.
THE DOMESDAY PROJECT
The BBC Domesday Project was launched in
1986. It was meant to be a modern equivalent of
The Domesday Book, using modern technology
(notably a laser video disc system) to store and
retrieve a massive amount of information about
general life in Britain,

Electronics new removable cartridge
hard disc systems can work on the

the new A5000) as well as on BBC
Master computers.
The secret lies in the hard disc
cartridge which after dismounting can
be taken o ut and sto red , o r be rep laced
by another cartridge within a few
seconds. Security isso easy with these
discs because you can simply take
them home or lock them away.
The unit can also be used as a
backup system for internal hard drives
as well. Once you have looked at the
prices you will see that they are
significantly cheaper than tape
streamer sytems. You also have
virtually instant access to the
information stored on them because
they are a hard disc and therefore it is
simply a matter of copying files from
one disc to another instead of having to
run lengthy restore programsto recover
information from tape.
Perhaps the biggest advantage of
these units isthat when one cartridge is
full then all you have to do is purchase
a new cartridge and not a whole
mechanism saving you a small fortune
in the process. The mechanisms can be
either 44MB or 90MB, however please
note that the cartridges are not
interchangeable between the two.
The mechanisms are true SCSI

PROGRAMMING
f you've been following this series, you will
know I promised to start ihis month with
some more information about negative num-
bers, I've already introduced the concept of the
twox complement method of representing nega-
tive numbers, and alt that remains is to tell you
how you can directly load registers with nega-
tive numbers. Unfortunately you cannot use (he
obvious: MOV ro.im .
The instruction that we use is mvn or Move
Not, but, to be even more awkward, you cannot
simply say: mvn ro,(M or even: mvn ru.#4.
For some reason best known to Acorn, you
have to supply the ones complement of the
number. Remember with twos complement you
change all the Os to Is and Is to Os and then add
1. Well, with ones complement, you simply
don’t add the I . The easiest way to do it with the
Basic assembler is to use the Basic keyword
not. This is more commonly used to provide the
’opposite' case in an [F statement, such as w not
flu^* THEN,,. In fact, NOT actually performs the
ones complement of its parameter - very handy!
You can therefore load a negative number
simply with mvn ri>.#not-4.
Some other assemblers, such as Acorn's own
macro-assembler Aaam, actually allow MOV w id)
negative numbers, and simply perform the
necessary bit-shuffling on the constant and
assemble a MVN instruction instead. Although
you might have typed MOV ro.# l if you have a
look at the actual machine code the assembler
has created, it will say MVN
it is not possible to supply negative numbers
as parameters to other instructions, it's a silly
example, but you cannot say, ADD rojrlh -56 as
some assemblers may translate instructions such
as these into more appropriate ones. You might
like to try typing in listing one in the yellow
pages, which demonstrates ihe use of simple
arithmetic on negative numbers. Try following
through the stages by 'hand" first to make sure
you understand everything as it happens.
HEXADECIMAL
Before moving on. I'd like to outline the basics
of the hexadecimal number system. Clearly,
referring to numbers in binary is quite contrived,
not to say time consuming: 'Pardon? Was that
1001 10 1 001 or 1 0010 1 1001?'
Because binary is all based on powers of two,
and 10 isn't a power of two, you cannot directly
use decimal, which is a shame, since most of
you will be used to that already! Some computer
systems use base eight, or octal, which uses the
decimal digits 0 to 7. Converting from binary to
octal is relatively easy - you simply take your
binary number and chop it into three-bit chunks,
which arc then converted to octal ( effectively
decimal in this ease).
For example, 92.1 in decimal is:
3 1 1001 10! I
001 1 10 01 I Oil
I 6 3 3
The number 923 in octal is therefore 1633, Note
this should be read 1.6. 3. 3 octal, to. avoid
confusion with one thousand six hundred and
thirty three. The disadvantage of octal is the
chunks of three - not a nice power of two!
Quadra! could be used (with two-bit chunks] but
then you’re almost back to binary.
So. hexadecimal is the most common notation.
This is base 16 and uses four- bit chunks of data,
and is often abbreviated to ’hex'.
Of course, decimal only has 10 digits, so the
letters A to F are used to represent the decimal
numbers ID to 15. Conversion to hex proceeds
as for octal, except in four-bit chunks:
IIIOONOM (923)
00 1 1 1001 1011
3 9 B
Hex numbers are often written with a preceding
■&' to avoid confusion with decimal numbers -
so 923=&39B- As mentioned before, one binary
digit is called a bit. Historically, eight bits arc
called a byte. This is derived from early compu-
ters which were eight-bit machines (like the

being a shortened form of bit bight,
So 32 hits are often called a word, although
some computer systems, such as the 68000, cal]
this a long word and use word to mean 16 bits.
Words are 32 bits long in the Arm. Going the
other way, half a byte (four bits, one hex digit)
is, of course, a nibble. And no. I'm not joking!
LARGER NUMBERS
Next on the list of things to explain is larger
numbers. Until now, Pve told you to keep the
numbers that you toad into registers under 236,
but not to worry about the size of intermediate
results. Last month 1 mentioned that the Arm is
a 32-bit processor and can therefore detd with 32
bits at a time. So, why can you not say mov
KturartT? After all. 987 in binary is only a 10-bit
binary number.
The problem lies in the way Arm instructions
are stored in memory and also explains why you
have to use the ones complement notation for
specifying numbers. In the first article in this
series, I explained that it is the job of the assem-
bler to translate the human’ words MOV. ADD,
mul and so on, into the appropriate sequences of
bits that the Ann understands.
One of the good features of the Arm is that all
iis instructions are encoded to the same length,
namely 32 hits (one word) Ii is a coincidence
that the processor is a 32- bit processor. Many
other processors ( such as the 6502. 68000 or
80x86) have variable length instructions. In
6502, ph a is only eight bits long’, whereas lda
&3l?t)0.X is 24 bits. In such cases it is common lor
the first byte for whatever) to be the base
instruction and, if necessary, subsequent bytes to
form parameters for the operation.
Anyway, back to (he Arm. When it processes
an instruction, it grabs a whole word’ instruc-
tion and examines certain hits (in both senses of
the word) to see what sort of instruction itis
dealing with. For example, if bits 26 and 27 are
clear (0), then the instruction is a simple data
processing instruction such as MOV, ADD<ir rsb.
With this in mind, she Arm can then make
sense of the rest of the bits. Certain bits have a
fixed meaning: bits 28 to 31 are the condition
code (more about these later in the series) but
others will vary according to the initial class' of
instruction. The important upshot of all this is
that all parameters for instructions have to fit
within these 32 bits, hence you cannot supply a
lull 32 -bit number to mov and so on.
YELLOW PAGES
To find the programs men-
tioned in this article, please
turn to the yellow pages,
under the section entitled Arc
Assembler. They can also be
found on the subscribed
monthly disc.
In fact, as you are allowed to supply a con-
stant on the end of ait addition: add ro.R4,jh>4. As
well as the 64’, those 32 bits have to store the
fact that: you have specified add; you are using
ktr and R4 anti condition code mentioned earlier,
as well as a couple of other twiddles which I
will come to later.
From the grand total of 32, this leaves only 12
bits to specify the constant. Rather than doing
the obvious, and making these 12 bits bits 0 to
1 1 of a 1 2-bit constant ( which w ould only allow
the numbers 0 to 4095), Acorn splits the 12 bits
into two fields, one eight -bit constant and one
four-bit shift'.
The shift is how many hits the eight-bit con-
stant is offset. This is the computer's way of
thinking about it - mathematically, the value
represented is: value >c 2 ( - * So, with a shift
of zero, you can represent the numbers 0 to 255;
with a shift of one; the numbers. 0. 4, 8, 12 , . .
1020: with a shift of two. the numbers 0, 16.
32 . , , 4080 and so on.
Unfortunately. I have to admit that this is a bit
of fib - the shift value doesn't really work in
this way. It is actually an offset in the opposite
direction, so my shift of one above is actually
stored internally as 15, two is represented by 14,
and so on. A real* shift of one moves the value
right and off the bottom of the 32 bits available.
But it doesn't just fall into hyperspace - bits 0
and 1 ‘wrap round’ and become bits 30 and 31
A shift of lour moves the value eight bits to the
right, thus all the bits wrap round, allowing you
to access the ‘top byte' of the 3 2- bit word.
Luckily you never need to worry about the way
constants are stored within the instructions,
since the assembler does all the work of convert-
ing your number into the necessary eight-bit
value and four-bit shift.
If a constant you give cannot be converted,
you will get an error such as Bad immediate
constant'. Therefore all values 0 to 255 are Fine
(they are all eight-bit numbers anyway), 256 is
line because only bit eight is set (to 1 ) so it can
be converted, however 257 cannot. Both bits 8
and 0 are set, so the value' cannot be represent
by an eight -bit number.
The more astute of you may have noticed that
because only four bits are available for the shift,
only 16 "posit ions' are available for the (he
value field. Because of this, numbers such as
258 cannot be represented.
Although the width' of the number is only
eight, (so bit 8 and bi( I are set) only one posi-
tion of shift is needed, which cannot be
represented with one of 16 positions available.
However, 516 is allowable since an actual shift
of two (shift field- 1 5, remember) can be used
with a value field of 1 29.
Although this system of value and shift offers
a more limited range of small' numbers, it has
the major advantage of allowing a reasonable
range of large’ numbers to represented as well.
Powers of two are often used within programs
for a number of reasons and, as these have only
one bit set. all 32 of them can be represen led.
BENEFITS
The even more astute of you will have realised
that numbers less than eight bits ‘wide' can he
represented in a number of ways: two. for exam-
ple, could be two with a shift of zero or one with
a shift of 15 - this is the inevitable redundancy
of this system, but l (hink you'll agree the bene-
fits far outweigh the problems. Listing two
shows some examples of larger numbers. You
won't be able to run this program as one of the
lines causes an error - can you guess which one?
One final point relating to negative numbers,
' -I’ in binary is represented by all Is (see last
month s article). Fairly obviously, this is 32 bits
wide' and therefore cannot fit into an eight-bit
value field. By using the ones complement
method, -1 becomes 0 which, as we all know,
w ill easily fit into eight bits.
Next month I will look at the final instalment
of mov and explain what you do if you really do
want to load 2581

The techno-! Real-Time Colour Video
Digitiser for Archimedes computers is
one of the most advanced video
digitisers available, with features usually
found only on top-of-the-range models
for the IBM PC.
The techno-l card, with RISC OS
multitasking software, allows you to
grab a picture from a video source (TV,
Video recorder, etc.) and convert it into
a sprite. This can then be dragged to
RISC OS applications such as art or
DTP packages.
Unlike simple RGB video digitisers,
techno-l handles colour in 25 bits with 7
bits luminance and 18 bits
chrominance. By manipulating the
image using hue, saturation and
luminance, it mimics the human visual
system. The colours are therefore truly
WYSIWYG, tech no- i will also give true
monochrome representation of colour
images.
The on-screen viewfinder displays live
colour or monochrome in real-time. The
viewfinder can be either 1/16 or 1/4
screen area, and can be offset vertically
and horizontally under user control.
The frame buffer resolution is up to 512
by 51 2 1 with programmable vertical and
horizontal resolution. Complex frame
manipulation features are built into the
hardware including options to grab the
current frame or previous frame and
grab the last completed frame.
All viewing, video and digitising
parameters are software controlled,
there are no presets, no setting up,
simply connect to a video signal, load
the software and digitise!

STRIKE A CHORD
YELLOW PAGES
As usual, this program is free
to subscribers on the monthly
disc, in both eight-bit and 32-
bit versions, if you do not sub-
scribe, you can still type in the
program by turning to the
Chords section in yellow pages.
The 32-bit user should type
in listing one and save it as
! Run image in a directory called
’Chords. Then create a Mode
12 sprite in Paint called
! Chords, with the dimensions
34 k 17 and save it inside the
■Chords directory as (Sprites.
Using Edit create an Obey file
and enter the following text.
3! RUN for Chords
WimpS lot -min 30K -max 30 K
RUN <ObeySOir>.!Runltnage
Save this Obey file as JRun
inside the (Chords directory.
Now double clicking on the
I Chords icon in the directory
viewer will run the application.
Eight-bit users should type in
listings three and four and save
them asChordsI and Chords!
Then CHAIN "Chords!".
i is common knowledge that playing a one-
fingered tune on a piano sounds pretty boring.
To make a tune come alive you need to play a
few well-chosen notes at the same lime - notes
which harmonise with the main theme.
Anyone who plays the piano will know that
certain notes, when played together, form a
chord. In published sheet music the accompani-
ment harmony is often shown using chord
symbols. Guitar players are lucky - they some-
times even gel a little drawing which shows
them where to put their fingers.
Some years ago, when 1 felt that the world
badly needed another guitar player. J learnt all
the chords I needed using songbooks and dia-
grams in a chord dictionary. More recently,
when I wanted to learn chords on a musical
keyboard, I decided to enlist the help of my
computer. Hence the birth of Chords .
The application Chords is a chord dictionary
with built-in sound, but it also has a simple
sequencing feature. Even if you are not learning
to play, just listening to the different chords and
the way they work together can be fascinating.
USING THE PROGRAM
The program installs on the icon bar in the usual
way. Clicking select over the icon brings up two
windows: one contains the music keyboard, the
other the selection menus.
On the left are the 12 basic chord names from
C through to B. plus control of the sequencing.
In the centre there are 15 chord forms: the basic
major and minor triads - triad means three notes
- and a selection of higher forms. (If you tire a
bit hazy about your harmonies, then take a look
at our box called natural progressions,)
I
Select the chord name, form and position from
the menus, and the keyboard window will show
which keys to press and what the notes are
called. Meanwhile, the chord is played through
the computer sound system and through a Midi
interface and keyboard, if one is Connected-
Pressing Adjust makes a selection without
running the demonstration.
Notes played on a Midi keyboard are also
shewn on the display so the piayer can confirm
the correct fingering. However, don’t play lots
of notes very fast as this may leave the program
behind and fill up the Midi buffer.
Each time the mouse is clicked on Play seq.
the next chord in a predetermined sequence is
piayed. To enter a sequence, click over enter to
reveal a line of text which can be edited in the
usual way. Rewind puts the sequence pointer
back to the start and Help displays a reminder of
the sequence notation.
When the Arpeggio option is ticked, chords
are piayed with a delay between each note. This
is not a true arpeggio but it makes the individual
notes easier to hear. Delay sets the delay in
centi-seconds - from five to 100 is reasonable.
THE LISTING
In the 32-bit version, the Wimp routines are
fairly straightforward, with windows and menus
defined within the program. The keyboard
graphics are drawn by PROCdniw_screen and PROC-
pk>i (which draws one key only), by first calling
PROCbfickgnd to direct all VDU driver output to a
background sprite. The usual drawing com-
mands are then used without having to refer to
window co-ordinates. PROCforegnd then directs
output back to the normal screen. When the
62 BBC ACORN USER APRIL 1992
YELLOW PAGES
window manager calls for a re -draw, the whole
sprite can be quickly plotted at the appropriate
screen co-ordi nates. If the user decides to
changes desktop mode, while the program is
running, [hen raOCdraw_screen redefines and re-
draws the sprite.
The selection window is constructed entirely
from icons (this method allows faster access
than Wimp menus). The window manager
numbers the icons in the order that they are
defined, so there is no need to save the icon
handle returned by svS"Wimp_Creaiektm“. To
determine what name, form or inversion has
been selected, PROCproras3„ieons merely checks
ieonvf against a range and subtracts an offset.
The presence of an A corn- compatible Midi
interface is detected in FNmidi by setting a local
error trap and then attempting to make a Midi
SWI call. The note number to send to Midi is
Ktt+S'J. where K is the key front I to 24. Change
59 to 47 to drop the sound one octave.
The data defining each chord is stored at (he
end of the program. For each form the root
position is given first, then the three inversions,
then the name for use in the menu. Our 24-note
keyboard is numbered from one to nine then A
to N. where 1 represents low C. 2 is C# and so
on. Only chords in the key of C are stored' other
keys are derived by adding an offset,
A more elegant approach would be to take the
basic triad and alter or add to it, according to a
formula. A whole range of altered chords could
then be produced quite easily. Some notes have
different names but sound the same, for instance
C# and Db Logic in PROCplav determines the
appropriate name to print on the keys but it is
not always grammatically accurate - another
reason why the chord data would be better
derived from a formula.
FNioo_high checks if any note would be beyond
the top range of the keyboard, in which case the
whole chord is moved down by an octave.
P R OCpI ay^seq ue rtce processes the sequence Lex l
using (N$tr to match the letters entered with
those valid. No error checking is performed
here. An unrecognised entry will default to a C
or a major chord, depending on where the error
is. You may need to alter "tuning so in
PROCinii_prog to adjust the pitch of your micro.
EIGHT-BIT VERSION
The eight-bit version works in a similiar fashion.
Selection is made using the cursor keys, a lick
indicating the selected item, return plays the
chord and space steps through the sequence,
Pressing to allows the sequence to be edited.
Insert editing is provided, using cursor left;
RrGHT, and delete. Press return when it is
finished. As there are only three sound voices
and many chords have four notes, notes are
played one-at-a-ttme in arpeggio style.
The program is in two parts. Chords contains
instructions and sets page to &130O ready for
Chords2, Data format is the same as for the 32-
bil version, but there is only room on the screen
for 14 chord forms, so the minor#7 has been
omitted. To save space, the sequence string is
indirected by seq 1 * to &AOO, No Midi output is
provided but could be added as indicated in
pRtXpijy. Midi input is not included but a routine
similar to PROCmidiJn could be added.

program menu there are four positions: the
root plus the first, second and third inver-
sions. The note that the chord is named
after is known as the root of the chord.
(Moreover, in a root chord - shown on the
right - this note is also the lowest note in
the chord.) Inversions are a re-arrangement
using the same notes, but where the root is
not the lowest note. To try out progres-
sions, in other words a sequence of chords that lead naturally from one to another, the
sequence option can be used. Chords built on F and G follow on from C pretty well.
Numerous songs have been written with just C F and G, known as the three chord trick, and
some rock groups, such as Status Quo, have built whole careers playing little else.
The tricky bit is to find a sequence which
progresses smoothly and at the same time
harmonizes with a complex melody. Each
chord form brings a different quality or feel
to the music. A major chord has an air of
finality: indeed, most tunes end on the
major chord of the key. A chord like O,
however - shown on the left - lends a
feeling that there is more is to come and so
this type of chord is often found in songs
at the end of a phrase or sentence. Play C7
and hold on to it for several seconds. The
ear feels uncomfortable. Something should
happen. Now play F Major The ear is satisfied. The C7 chord has resolved on to the F Major.
Sharpening the fifth (that is, the fifth note up from the root) of a major chord gives an
augmented triad, which tends to resolve on to a chord with a root a fourth above it's own,
(try C plus F). Any note of the augmented can be the root and this applies also to the
diminished chord. Compare Co Ebo Ftfo Ao with Co ICo 2Co 3Co,
To hear a diminished chord at work, try C
Co Dm 7 G, Here, the diminished (see right)
resolves into a minor, and the minor to G
Major. Notice how it sounds unfinished.
Following on with the reverse, G Dm7 Co C
gives a complete progression, but the two
G$ together sound dull. Would Gsus4 be
better than the second G 1 The minor sharp-
ened seventh (m#7 for short) is an example
of an altered chord that definitely belongs
in a mystery movie! Inversions, although
containing the same notes, don't always
have precisely the same effect. C major in
the 1st inversion doesn't sound quite as final as the root position. Play C Major seventh
(Cm?) in the root position and the notes look evenly spaced, Move to any of the inversions,
and B and C pop up next to each other. Being adjacent, they sound discordant on their own,
but in harmony with E and G, the sound is, well... judge for yourself!

A TIGHT FIT
Laurie Junes of Bedford
— continues our curvy theme
this month with CunwFir,
This is a program which
uses an iterative procedure
to reduce the size of a for-
mula which represents a
- curved line. Using an
& expression of x with two
parameters, a and h it will fit
any two parameter function of
x. The menu gives a selection
of functions which have pro-
ven useful, but allows the
entry of any expression in the
correct form; for example, y =
a + bf Xar y = a f 0 + b*X).
The usual method is to
transform the data into a linear
form and then to perform a
linear regression. Unfor-
tunately this gives unequal
weightings to the data points,
depending on the transforma-
tion used. By using the speed
of the Archimedes to perform
simple iterations, you can
avoid the use of sophisticated
curve -fitting algorithms for
non-linear data, provided the
theoretical curve is known,
The basis of this program is
sequentially to optimise the
values of the a and b parame-
ters, starting from initial
‘guessed" values (the default
value is one).
The xv data set is read into
an array, and the calculated
value of y is found for each
value of x The observed y
v a lue is s u btracted a nd the
result squared. The squared
values are summed for each
.v,y pair to give the initial sum
of squares. The value of a is
then decreased hy 10 percent

and the process repeated. If the
sum of squares has decreased,
a is again reduced and the pro-
cess repeated. (Otherwise the
direction of change in a is
reversed and a is increased.)
This process is repeated
until the sum of squares again
increases. The direction of
change is then reversed and
the step size reduced to 1 per-
cent. The iteration continues
until the next overshoot', the
step size is reduced to 0. 1 per-
cent and direction reversed
again. This process continues
until the step size is 0.00001
(which can be altered at will).

Example data for curve fitting
The same procedure is then
run to optimise /?, The cycle of
optimising a and b alternately
is continued for 50 cycles or
until the ratio of the sum of
squares of y on successive
cycles is between 1.00001 and
0.99999 (again arbitrary}. In
principle the same system
could be used to tit a third
parameter* hut (he fitting pro-
cess would be very slow.
The data should be stored in
a previously prepared data file
- the required format of the
data file is described later.
Once the data file has been
read, the program plots out the
data points on automatically
sealed axes and then presents a
menu containing a set of curve
options, plus an option to enter
any other function of x in
terms of a and b. The iteration
then proceeds, is monitored by
a counter and timer, and the
display of the ratios of succes-
sive sums of squares.
Provided the curve chosen is
appropriate to the data, and
sensible a and b values were
BBC ACORN USER APRIL 1992 65
chosen, the iteration takes a
few seconds to a minute or so,
depending on the amount of
data to be fitted.
The program then prints out
the values of a and b and the
function fitted, together with
the residua] sum of squares
about the tilted line and the
root mean square. The curve of
best fit is then drawn on the
plot of the original data points.
By using a Mode 36 screen, it
is possible to show the curve
parameters and the fitted line
on the same screen, and print it
out if required. Next, an anal-
ysis of variance is produced,
showing the total sum of
squares for y, the sum of
squares accounted for by the
regression, and the residual
sum of squares.
The variance ratio, F, gives
an estimate of the significance
of the fitted line for the num-
ber of degrees of freedom in
the data. If the curve fitted was
a straight line then the regres-
sion coefficient r is printed.
The main use of the pro-
gram is to fit calibration
curves to biochemical data and
[hen to use these curves to cal-
culate the concentrations of
test samples. In setting up the
calibration curve a set of sam-
ples of known concentration
are used, and appropriate
instrumental readings taken
(for example, colour measure-
ments, meter readings and
radioactive counts).
The concentrations are
plotted on the x axis, and the
observed readings on the y
axis. Once the curve is estab-
lished. the values obtained
from test samples are read, and
the concentration determined
from the calibration curve.
A I though this would not be
the method of choice for per-
forming linear regressions.
comparison with ihe standard
method gives the same values
for [he slope and intercept, and
the same residual sum of
squares to three or four deci-
mal places, and could be made
closer by increasing the num-
ber of iterations (modify the
value of 'factor' at the end of
PROCiieratt and/or the limits at
the end of PROCopdroisc). No
cheeks have been made with
other curve fitting procedures.
As mentioned, data for the
program should be stored in a
file. This can be created using
Edit. The file should contain a
heading for the graph, a label
for the x-axis and a label for
the y-axis (maximum of four
characters) on separate lines
followed bv the data in the
form of x_v pairs, one per line.
Blank lines and lines begin-
ning with a semi-colon are
ignored, so you can add in
comments if you want as
shown in our example file (on
the previous page). If you’re
feeling particularly unctuous
you might like to SeiTypc your
file to a CSV and load the file
into a spreadsheet!
There are some datasets that
will confuse the program, es-
pecially if the function you are
trying to fit is inappropriate, or
the original guesses of a and h
were a tong way out.
For some functions of x, it
will find false optima, where
the sum of squares seems to be
at a minimum. In these cases
an obviously silly line may be
plotted. In particular, re-
entrant functions such as para-
bolas or trigonometric func-
tions (sine or cosine etc) seem
to confuse it.
You can speed up the itera-
tions by omitting [he monitor-
ing of the process - there are
two calls to PROCmonitor in
PRQCopomis*. It is quite fun to
watch the successive attempts
at fitting the curve by putting
in an extra call to pROCdivw in
either the PROCoptimise just after
opUwp+=l- To really see what's
going on, you could try adding
a call within the Re-IPK.aT loop
of PROCirerale, but it will drasti-
cally slow things down!

PAST CORNERING
^ Our coveted star prize this
month goes to David
. Break well of Addlestone.
* Prompted by the Pieces of
C Eight revival of Bezier
^ curves (BAU December
91), he has rattled off a
speedy curve plotter for
. eight-bit machines. As you
may or may not know, there
are two ways of drawing
Bezier curves. The simplest is
the parametric method as used
by George Blanchard in Pieces
of Eight. This is a nice, con-
cise method that can be easily
translated into Basic and
involves a third variable,
usually t. that varies from 0 at
the start of [he curve to 1 at its
end. Values for both x and y
are calculated from r.
Another way of plotting
Beziers is to use a recursive
sub-division or 'divide and
conquer' method. The advan-
tage of this is that it can use
integer arithmetic throughout.
The only maths involved is a
divide by two which can be
performed with a simple right
shift on the 6502 processor.
The recursion works according
to the following rules.
'To plot a Bezier curve using
points ti. b, c and d. where a
and d are the start and end
points and b and t are the two
control points, calculate the
mid points of ab, be and cd
(call these e> f and g). Then
calculate the mid points of ef
and fg (h and i). Finally calcu-
late jf, the mid point of hi. Then
plot the two L sub‘ Bezier
curves aehj and jigd. This
should, of course, be done
recursively.'
Our diagram below should
make this dear. To stop the
recursion a 'depth' should be
passed down the calls and
once this reaches a predefined
level, the straight line ad will
be drawn instead of recur sing.
Alternatively, and more effi-
ciently. a quick check could be
made at the start of the routine
on the length of this line seg-
ment and the recursion then
only lakes place if is is longer
[ban, say, four pixels.
We've knocked up a demon-
stration, entitled BezDento.
that plots a curve using para-
metric and recursive methods.
Drawing a bezier curve using a
recursive sub-division method. All
points e-j are mid points. Each sub-
division generates one more point
(j) that is guaranteed to be on the
curve.

As David's machine code ver-
sion uses operating system
VDU calls to do the plotting, it
will work on any eight-bit
machine in any mode, includ-
ing shadow modes. This does,
of course, mean that it might
not run as last - directly
accessing the screen memory
would be quicker - but it does
remove the need for compli-
cated bounds checking for the
edge of the screen and
graphics window. Also it
makes this version indepen-
dent of screen mode,
David has included a short
demonstration of Itis code in
the listing, that merely plots
random curves. From this
demo, the way that you use the
program should be fairly self-
explanatory.
For curiosity value only, he
has also sent in a routine that
renders Rise OS Draw files on
a BBC. For those interested,
this can be found on the
monthly subscribers* disc.
Needless to say. it doesn’t han-
dle line widths, filled shapes,
colours, text, sprites...

this month with a very
nice seven line procedure
for Arc users. The offering

eight shades of 27 colours
in 256 colour modes. The

peoples’ lives, so it's nice to
see a short way of making
sense of all those hues!

sure to press s when the pro-
gram boots between each

you run the program, there is
one example of a recursive
flower, which you have to stop
by pressing SPACE.

PLOT SPOT
From our reader survey it
seems that many of you
would like some back-to-
basics stuff, to assist you
with Basic and machine-
code programming. We’ll
try to respond as best we
.can to these and other
comments from the survey
in future issues. M J Ballinger
of Cirencester has asked how
to plot a point on the screen of
an Archimedes using machine-
code. This being the basis of
literally dozens of items in
past ★INFO articles, we
thought it would be a good
point to kick off with, so have
a took at Point32 ,
You can plot points using
the Basic keyword POINT or by
using 'official' calls. However,
it is much quicker to 'poke'
points directly into the screen
memory. The screen of the
Archimedes is arranged very
simply and 256-colour modes
Layout of th6 Archimedes’ mode

are particularly easy to deal
with. This is why so many of
our demos run in modes 13 or
15 and Point 32 uses a 256-
colour mode for precisely the
same reason.
That reason is that in
mode 13, for example, each
point on the screen is repre-
sented by a single byte. You
simply choose the colour you
want from the 256 available,
work out which byte you want
to poke and put that value
there. Each row of pixels

(starling with the lop one) con-
sists of a block of consecutive
bytes of memory as shown in
the previous diagram.
In mode 13 there are 320
pixels across the screen, so the
top row occupies bytes zero to
319 of screen memory. The
next row follows on directly
from this, so it lakes up bytes
320 to 639, The next uses 640
to 959.
Unlike the BBC however, it
is nol always obvious where
the screen starts in memory. It
depends on how much of your
machine’s Ram is allocated to
the display. There is a call
which allows you to find ihe
address of the top left comer
of the screen though (column
zero, row zero in figure one)
and this is OS.ReadVctu Variables.
It takes two parameters - the
first points to a list of numbers
terminated with one. The num-
bers are the codes for the VDU
variables you want to read.
Code 148 means the start of
screen as used by PLOT and
draw. The second parameter
points to where you want the
values returned to be placed. It
may be the same place, as in
the example, if you're only
going to read them once.
The plot routine in the
example is called .plot and
takes three parameters. In
registers R0 and Rl (taken
from A% and B% in Basic) are
placed the co-ordinates of the
point to plot. Note that these
are not OS co-ordinates but
'raw* values (x in the range
319, y in the range 0-255). The
colour to plot is passed in R2
(C%). To calculate the screen
address, we use the simple
formula: address = base + y x
Unelength 4- v.
The value base has been
read with OK_RcaclVtiu Variables
and line length is 320 for mode
13. We could use a multiply
instruction to calculate the
address of our pixel, but
because 320=256+64, we can
use two shifts instead and this
will be much quicker. Also,
we don't need to add on the x
because we can incorporate
this into the Strb instruction
that places our colour on the
screen. The example plots a
line of randomly coloured
points by repealed I y calling
.plot. For speed, you would nor-
mally reserve a register to
permanently hold the start of
screen address, so it need not
be reloaded each lime.
Having looked at machine-
code graphics at their simplest,
let's take a bit of a leap and
sec what else can be done.
Cube uses the same principles
as Point 32 - mode 13 is used
for speed and simplicity.
Three pictures are loaded
and then mapped on to the sur-
faces of a rotating cube. Since
it was readily available, we
have used the output of Jan
Vibes' Tonerl? and saved
them as mode 15 screens with
ihe names picjtree, pic_flower
and picjtiies. Alter the listing
if you want to use other sprites
- any 256-colour ones will do.
whatever their size.
The program uses a cheat to
perform the 'squashing' of the
sprites into arbitrary quadrila-
terals. The technique is fast
and simple, and convincing
enough if the sprite is not
stretched too wildly! Our
example shows the basic idea,
with a sprite A BCD being
mapped on to A'B'C'D',
To do this properly would
mean applying a transforma-
tion to each pixel in turn and
Squashing a rectangle
BAU Health Warning: not a program to run when you have a hangover
this would lake many seconds.
Instead, we find the lowest
point in A'B'C’D’ - B' in fact.
Then we move up the .shape a
row at a time. With each row
we see how far along B'A' we
arc, and how far along B’C,
We then mark points with
the same proportions along BA
and BC and draw a line
between them. Finally s we
simply take this line and
stretch it or squash it, so that it
fits on the current row we are
plotting, then move up another
line and repeat the process.
Eventually we reach the row
that C lies on. We take note of
this and continue upwards.
We're still moving along B’A'
on the left, but are now mov-
ing along CD' on the right.
Again, we lake points from the
original shape that are the
same proportions along BA
and CD, draw' a line and map it
on to our new shape. A little
further up we encounter A' on
the left, so start moving along
A'D’ on that side, continuing
along CD’ on the right. Finally
we reach the top.
Because we’re plotting
actual rows on the screen, we
can use fast store and multiple-
store instructions. Also,
because we are only concerned
with each point on I he final
image, holes will be filled in if
the image is bigger than the
original and smaller versions
will be plotted more quickly.
The cheat becomes apparent
if you stretch one comer a
great deal - a fold will appear
in the image. The picture is not
really treated as a single piece
of rubber (which would be
ideal) but as several pieces
joined together. Still, the
effects arc good enough, and
the speed is sufficiently fast to
make the routine useable in
real-time.

that. Uptime keeps a record of
when you have used your Are
and can also be used to detect
usage of the given Are in your
absence. However anyone who
is able to manipulate text tiles
could cover their trail, so be
warned! Once installed and
included in an autobocu
sequence, UpTime h com-
pletely transparent.
Recording ihe time of start-
ing work is quite easy. lust
after switching on - or going
up as we will call it - UpTime
is run as pari of the autoboot
sequence. As well as other
actions, UpTime then reads the
RTC {Real Time Clock) and
writes it's value to a file. This
file called UpTime Log acts as
a simple kind of logbook.
Not surprisingly, the time of
going down fin other words,
switching off) is not as easy to
record. If you are very discip-
lined you could write some
kind of closing down sequence
and execute it every time you
stop work. Part of such a
sequence could be a program
that writes the RTC- time to the
file UpTtmeLffg but, of course,
it is far more convenient to
have the lime of going down
recorded automatically -
To achieve this. UpTime
continuously writes the time of
the RTC to Cmos Rant. The
data in Gnos Ram is preserved
by battery when the Are is off.
So, a! the next Lime of going
up UpTime reads the time in
Cmos Ram and writes it to the
file UpTimeLog. This time
represents the time of going
down because it was the last
one written in Cmos Ram.
To reduce the load on the
processor, writing the RTC
time to Cmos Ram is limited
to once a minute. By doing so,
the resolution of ihe recorded
time is also one minute. Care
is taken to perform proper
rounding off when converting
cent i seconds to whole minutes.
Again, to reduce the processor
load, no use is made of
Wimp_EVll oi Wimp^PoUlJlc,
The Wimp desktop polling
mechanism is not used for two
reasons. Firstly, the writing to
Cmos Ram would grind to a
halt if you left ihe desktop.
Secondly, general polling is a
rather inefficient method. Rise
OS itself provides the perfect
solution by means of a couple
of SWIs. namely OSJTallEvery
and OS_Re moveTickerEvcn I .
0S_Cd!Ev«y is used to install
an interrupt routine on a timer
chain. Once installed, the rou-
tine is called repeatedly after
every fixed time interval.
OS.RumwfTirkffEvim is used tO
remove the routine from the
timer chain. UpTime uses
OS_Ca1 (Every with a time inter-
val of 6000 ce mi seconds (one
minute). In this way, once a
minute, action is taken in the
form of writing the RTC-time
to Cmos Ram and the Arc is
not slowed down by running
yet another desktop task in the
background.
In Cmos Ram. the locations
30 to 45 are reserved for the
user. The time and dale of the
RTC can he stored as a five
byte value. Obviously, claim-
ing five of the sixteen
locations available is too
much. Instead of storing the
absolute time and date, a rela-
tive time is used which
requires only two locations in
Cmos Ram. With the minute
os a unit of time, just over six
and a half weeks can be stored
in these two bytes. Anything
relative must be fixed to
something absolute. In ihis
ease the relative time starts
ticking from a reference time.

Spired Graph Is a graphics card for the Archimedes, It will provide resolutions or up to 1024 x
766 pixels with 1 6 colours and 800 x 660 pixels with 256 colours. High screen refresh rates
guarantee professional working. But this will not slow down the computer; in the contrary, It will
even make it faster So Speed Graph gives you two advantages,
high quality graphics and - at the same time - high speed.

To allow ihe RTC to bo sot a
tittle backwards, the reference
time is the time of going up,
minus one week. As a conse-
quence, the maximum period
of slaying up, in which ail
timekeeping makes sense, is
limited to about five weeks.
There is no need to worry
should this period be exceeded
since nothing dramatic will
occur. Everything will go on
except the time of going down
will be calculated incorrectly
as the reference time will no
longer be valid.
The part of UpTinte respon-
sible for updating the Cmos
Ram every minute, is held in a
relocatable module called
UpTime Logger, This module
is assembled every time
UpTitne is run, because the
reference time must be known
to (he code in order to convert
the RTC time to the two-byte
relative time.
Therefore, the module is not
saved to disc but transferred
directly to (he RMA by using
QS_Module with RO set to 11.
The module help string con-
tains the date of assembly but
the version siring stays fixed
to one. The figures on the
previous page contain the
!Boot and !Run files and
should be entered using Edit
and saved in a directory called
lUpTime. The main listing,
IRuntmage, is on the yellow
pages. You will also need to
create a suitable sprite with
Point and save it in the
/ UpTime application directory.
The actual logbook file
UpTimeLog and the reference
file UpTimeRef are not listed.
These files are created and
updated by the application.

MASTERMIND TWO
In January’s ★INFO, we
carried a neat little Mas-
termind program by J A
McHugh. We also asked if
any bright reader could
come up with a good
computer-play routine,
One who did is Malcolm
Gray and we’ve merged
his thinking routine with J A
McHugh's original to produce
a complete game. You can
now take turns with (he com-
puter, guessing its randomly
chosen code and then choosing
a code of your own for it to
work out. Although it may be
tempted* the computer doesn't
cheat and instead uses a ‘brute
force’ method to work out
your combination. Essentially,
ail possible combinations are
stored in an array and are
‘crossed off if they contradict
the results of previous guesses.
The computer usually man-
ages to get the right answer
within eight guesses and a
score is kept. Ten points are
awarded for guessing at the
first attempt, nine for (wo
guesses, eight for three and so
on. You might like to enhance
the thinking process by adding
a random element. Currently,
the computer will always
choose the same strategy, so if
you discover a code that it has
trouble with, it’s up to your
good sportsmanship not to rep-
eat the formula in every game!

Circular arguments?
It will soon be summer again and once more fields all over the
West Country will be full of crops, meteorologists, psychics and
sceptics. Will Doug Bower and Dave Chorley be at it' again with
pole, plank and string? Will the Plasma Vortex rear its ugly head
or will Jimmy Page merely be out with his Box Brownie in search
of album covers. Who knows?
But until the first circular speciality ihis year, perhaps you'd
like to have a go at what Doug and Dave did with our specially
written one-liner. Type in the listing as it is and squash it with the
key definition below - the program won's run properly on
multiple lines. The program will run on all Acorn machines and
will present you with a beautiful
field of golden corn swaying
gentle in the summer breeze,
Doug and Dove are represented
by small dots and start off in the
bottom left hand corner, G, H, J
and I will move them, and,
naturally D swaps between who
you are guiding. Pressing L will
flatten the corn in a straight tine
between the two hoaxers and the
O will make a mystical circle
with the selected man ai the
edge and the other a! its epicen-
tre, Rings can be formed by
creating a second circle within
the first - the pranxters wilt
magically stand all the com
upright again.
Complex patterns can. of
course, be formed by combining
these basic shapes. If anyone
creates any particular master-
pieces* we at the puzzle page
would be delighted to see your
efforts...

Tiler
A printing utility
which allows you
to print Draw and
Sprite files at any
size using any
type of printer.
The user simply
loads the required
draw or sprite file into Tiler
specifying the size of poster
required, either by using one of the preset paper size, eg. A2, AO,
entering the exact dimensions of the poster eg. in millimetres or by
expressing the size as a
percentage of the original
size. The document will
then be increased or
decreased in size
automatically and printed
when required over
several pages with crop
marks and references
provided on each page to
assist cutting/overlapping.

OPEN SYSTEMS INTER NETWORKING
Acorn have had the foresight to write software to allow common
links to many types of machines.
The protocol which allows this is TCP/IP (Transport Control
Protocol/ Internet Protocol). This defines the packets which travel
over Ethernet.
Chameleon sell products which allow Terminal emulation. File
Transfer X Windows terminals end allow you to use the hard disk on
a Sun type Network filesystem [NFS).
These products let us link : ACORN, APPLE, IBM PC and most UNIX
machines also usefully connect to Novell Fileseivers,
Pleads do not hesitate tj contact us to discuss your connectivity
problems (UNIX not required)
E CONET IS DEAD - LONG LIVE ETHERNET!
At last the A3000 has an Ethernet Adaptor!
This means that all ACORN Rise machines
can be internetworked leaving Econet to
the trusty 6502.

SPRITE
Converting sprites to draw files provides
many advantages. GRAHAM WALTERS
looks at a new package to help you out
C reating draw files from
sprites, and your own out-
line fonts, are the benefits
of a new software packages,
called Trace. The advantage of
converting sprites is that,
quite apart from the consider-
able reduction in file size,
draw files can be sealed and
manipulated to any size, with-
out any loss of resolution.
DOUBLE ACT
Trace actually includes two
applications. Trace and
1)2 Tout. The former does the
file conversion, while the latter
converts draw files into outline
fonts. Clicking select on the
Trace icon opens the two main
windows which, although ini-
tially blank, will eventually
show the original sprite file
and the convened draw file
(see the screenshot below).
On the main menu, if a
draw file has been created,
there is a facility to save it
either to disc or directly into
another program, otherwise
this option is greyed out. It is
also possible to save the sprite
image itself. To initiate [he
tracing of the sprite, you use
[he Trace option and you can
watch the draw file being cre-
ated in the draw window - the
pointer becomes an hour glass.
Choices leads to a submenu
with two Error and Save
options. Error determines how
closely the draw file corre-
sponds to the sprite file. A
large value will give a poor
rendering of the sprite file,
whereas if the number is too
small, it will reproduce the
individual pixels of the spriic.
A figure between 0.6 and 0,8
gives good results, although
trial and error is required for a
specific image. Save lets your
current Error value become the
default setting,
Info tells you of the mode,
number of colours and size of
[he sprite and draw images. If
you have a number of sprites
to trace, you can place them in
a directory and drop this on to
the icon. Another directory
called Draw is automatically
created and you can then trace
each sprite in turn, placing the
resulting draw file in this
directory. After tracing* a
sprite can be loaded into Draw
for fi nai [ wea king, a It h ough
this was not necessary for
most of the sprites I [ried.
The type of sprites that
Trace definitely does not like,
are those with any dithering or
graduated fills - they generally
give very poor results.
However, by re-working these
areas in Paint first, a better
result can be achieved,
OUTLINE FONTS
The second application,
D 2 Foul, loads itself in the nor-
mal way. Clicking on its icon
opens a grid window which
has a small light grey character
in the lop left hand cornet' of
each box. to show you where
to drop each draw file.
One annoying point was that
positions for Ascii code num-
bers 128 to 159 are shown in
the "tid as hexadecimal num-
bers. These characters in your
font are accessed by pressing
the Alt key and typing the
character's Ascii code number,
hut it would be belter if the
Ascii code numbers were in
deci mal Doub le c lick i ng
Select over one of the charac-
ter squares brings up a window
showing a larger version of
that character, complete with a
red line underneath. This rep-
resents the base line of the
character, which can then be
resized by using either Select
or Adjust.
Normally, you need to make
red line slightly larger than the
character outline. For charac-
ters with tails - such as a
lower case p - the red line
needs to be moved up to keep
all the characters in line.
When you have 11 ni shed
compiling your grid, a Save
Font option presents a direc-
tor icon that contains the
Outlines and ImMetries files.
This directory is then copied
into your current fonts appli-
cation. One word or warning.
Unlike a normal file, you can't
rename a font directory to
change the font name, so make
sure that the font is saved with
the correct name,
CONCLUSION
Both Trace and D2Fom are
very easy to use and perform
their tasks extremely well.
Overall, the package repre-
sents excellent value for
money and is suitable for both
school or home users.

What does everyone who creates
moving pictures want?
Render Bender is the graphics package that allows the
user to produce remarkable animated graphic sequences
using Ray Tracing.
Ray Tracing isn't nearly as complex as it sounds.
Basically, in a ray traced sequence, every pixel on the screen
takes aJI relevant light sources into account. Ensuring that
all the reflections and refractions are correctly calculated
even if the light is reflected off several surfaces* The image
could be no more faithful if you were filming real objects in
real light* To produce such a superb animated sequence,
however, was quite a difficult task - Until now.
Illuminator has changed all that. It is a fully RISC OS
graphical front end to Render Bender, Allowing the user to
create a series of frames manually, or to give it a start point
and an end point, leaving it to generate the frames in
between. What you are getting is the ability to take a sneak

preview. You can see what you are going to get, before you
get it. After you've created your outline frames in Illumina-
tor, you then transfer the files to Render Bender, the fully
RISC OS Ray Tracing part of the
package. Which all means that
now, to achieve powerful 3D Ani-
mation, you no longer have to be a
mathematical genius. You Just
have to be the proud owner of

RAM UPGRADE
MEMORY LAPSE
The A310 is sadly lacking in one vital area.
MALCOLM BROWN looks at how you can boost its memory space
• Regular users of an Archi-
Vj modes A3 10, not to men-
H lion the A305, w ill be well
aware of the limitations of (he
memory supplied. For
instance, if you load Up Draw
and Edit on the icon bar and
then draw a reasonably com-
plex figure, suddenly there's
no room left to write about it.
The answer is, of course, to
add more Ram, The A3 10 can
handle up to 4Mb of Rum
without flinching and several
manufacturers have come up
with upgrades which allow
you to increase the power of
the A3 10 considerably.
There are two sizes of Ram
board commonly available -
2Mb and 4Mb. Bear in mind
however that these sizes refer
to the tola! Ram in your
machine after fitting, rather
than the amount of extra Ram.
The 2Mb upgrades use the
existing Ram in your Arc. (If
you have an A305 you may
have to upgrade to 3 Mb before
tilting,) The 4Mb upgrades, on.
the other hand, add 4Mb of
Ram to your machine, and the
existing on-board Ram
becomes redundant.
Since Ram is relatively low-
priced, it makes sense to go
straight for the 4Mb and this is
the type we have chosen to
look at in more detail. It’s also
a good idea to fit a Memela
upgrade (a memory control
chip) while you're at it. Inci-
dentally, if you believe that
one day you might want an
Arm 3 in your Arc. bear in
mind that some Ram upgrades
limit your Arm3 choice. It is
worthwhile checking with the
manufacturers first.
The 4Mb upgrades fall into
two categories - those you can
fit yourself, as they can be
simply plugged in, and those
which you are advised to have
fitted by an expert, since they
require some delicate wiring
and soldering.
PLUG IN
With this type of upgrade (see
out Watford and Ground Con-
trol boxes), fitting is simply a
matter of removing the Memo
and Arm chips, and fitting
them into the sockets on the
new board, then luting the new
board into ihe old sockets.
However, removing the two
chips from the main board is
not easy, even with (he tools
supplied from the upgrade
manufacturers. You should
also remember that these
devices are easily damaged by
static electricity - walking
across a nylon carpet can gen-
erate up to 10,000 volts in
your body!
WIRED IN
The cheapest option is a
directly wired- in solution (see
our Atom wide and If el boxes).
The memory board is plugged
into specially installed sockets.
These are simple 16 and 18-
pin sockets and cost only a few
pence but you do have to do a
lot more work to connect up to
these lines. Many other con-
nections must be made to
various parts of the Arc's
existing memory and to the
Memo chip.
Removing the old memory
chips and installing these
sockets is not for the faint-
hearted or the inexperienced.
The upgrades are cheaper but
if you do try it yourself, yon
could make some expensive
mistakes: Instead, it is best to
leave it to the experts and use
the fitting service provided.
CHOOSING A BOARD
For this review we looked at
two plug-in boards and two

innately, the cheapest board
around (£155 for 4Mb) from
Simtec, (0772) 812863. was
undergoing a design revision
at the time of the test and so
could not be included.
When making ll decision,
the first choice is whether you
can bear lo be without your
beloved Arc for a day or so. If
the answer is no. then self- Th-
ing is the only option and you
should go for Ground Control
or Watford because of their
installation simplicity. Of
fiddly resistors need to he

looks extremely similar lo

The A torn wide upgrade

This is a four- layered cir-
cuit board so there should
be no line noise problems,
even when ihe machine is
subjected to the hardest
w orking conditions.
these two, the Watford board
must win out because it is a
four-layer construction, but I
would tike to have seen some
additional insulation .
The cheaper option, and per-
haps the better one in terms of
compatibility with further
upgrades, and the likelihood of
it staying pul in your machine,
is a hard-wined board. 1 1 el

GROUND CONTROL
Self-fitting board
Price: £243
Tel: (0635) 524008
This board is of the easy,
self-tit kind At first glance it
looks extremely neat and
compact. However, all is not
as it seems. First off, this is a
two- layer board. It has no
ground plane layer under-
neath the tracks on the
surface: these are used to
guard against electrical noise
which can interfere with the
data and corrupt the micro-
processor operation.
What's more, the use of
conventional (rather than
surface mount) chip plugs
and sockets has created a
design with small sub-boards
holding the sockets for the
Arm and Memc. This
lengthens ihe tracks at risk
from noise. Also, one logic
chip on the board has sev-
eral unterminated inputs -
again bad design practice.
However, it must be said
that we found no problems
of noise during ihe review
and such troubles would
usually only show up in a
heavily loaded Are.
Full marks to Ground
Control for using the top
quality McKenzie plugs for
the Ann and Memc on this
board. These require
minimum force to insert
them into the sockets. Just
as well, since the fitting
instructions suggest that
you leave the main board in
place, so it is put under
some strain when you press
home the new board.
All in all. rather more
attention to detail would
make this board cheaper to
produce and a clear winner.
WATFORD
ELECTRONICS
Self-fitting board
Price: £265
Tel: (0923) 237774
Another self- Hi board, this
upgrade is thoughtfully sup-
plied with a chip removal
tool for the Arm and Memc,
However, this is not ncc-
cesary, since a small screw-
driver works much better.
Also provided is a new
floppy drive cable - the
Ram board gels in the way
and a longer cable is needed
to snake around it.
Once the Arm and Memc
chips are removed, the
upgrade board is plugged
into the empty sockets on
the motherboard. A second
board then slots into place
and is used to hold the relo-
cated Arm processor. So to
upgrade to an Arm3 simply
involves unplugging this
second board.
Again the instructions say
to leave the main board in
place during the installation.
Given Watford's choice of
low-cost plugs, more pres-
sure was required to fit the
upgrade to the main board,
putting it under some strain.
The smaller board fits up
against the metal side of the
Are and is insulated wnth
only a sheet of clear plastic.
This could easily be pierced
by a pin causing a short cir-
cuit and on the review
sample, this had already
happened. However, the
upgrade is otherwise w r ell-
made. It is a four layer board
(although the sub-board is
only two- layer) and, if you
add a bit more protection to
the smaller board, it is an
excellent design.

WORK OF ART
Is this the moment that designers have been waiting for?
ROB MILLER looks at the release of Artworks
a omputei Concepts is a com-
pany renowned for its high
quality software. One case
in point is its desktop publish-
ing package Impression 2,
which is used to produce BBC
Acorn User,
So the announcement of Art-
Wo tics, CC’s new design
package, has been causing
something of a stir among
BBC A30OQ and Archimedes
users. Will the new package do
for design what Impression has
done for DTP? We were
invited by Computer Concepts
to have an exclusive preview
of the new ArtWoHfe. package.
An Works is best described as
a high-quality design package
and was used to create all of
the images shown here, includ-
ing the very impressive picture
of a Mini, shown above.
The package is designed to
be easy to use. yet is also
sophisticated enough for the
professional user. So what is
ArtWorks capable of?
OBJECT-BASED
Firstly , ArtWorks is not a
painting package. Although it
is used to produce pictures, it
is an object-based program (in
the same way as Drew) and
BBC ACORN USER APRIL 1992 95

HOW TO DRAW THE LINE
I he preference option displays
a menu covering the different
tools available. Key shortcuts
can be customised to allow
quick access to different tools.
You can alter: angle con-
straint (which effects the angle
that objects can be rotated to):
page units: font units: the
appearance of the text cursor:
the appearance of the toolbox,
and the way in which draw
tiles are loaded to. and saved
from An Works,
As there arc now two differ-
ent Draw formats (Rise OS 2
and Rise OS 2) ArtWorks needs
to know which one it is deal-
ing with. There are also some
features in A rtWorks which
cannot be shown directly in
Dm w - graded fills for exam-
ple - so there is also an option
to set the quality level in a pic-
ture when converting from one
program to the other.
RUNNING ARTWORKS
Clicking on the Artworks icon
produces a blank window and
clicking on this brings up two
other windows - the toolbox
and the info bar.
Both windows arc panes,
meaning that they are actually
a past of the main window and
move about whenever the
main window is repositioned.
This option can be changed in
the preference menu.
In keeping with the modular
nature of ArtWorks* tools are
organised into obvious groups
in the toolbox window. Tools
of a similar nature that are not
shown on the toolbox can be
accessed by clicking Menu, as
you would with a conventional
Rise OS menu. The toolbox
itself is editable: tools can he
rearranged, removed or added
builds up images of lines and
shapes, rather than using
individual pixels.
Every object within An-
Works - whether it be a line,
shape or text - is treated as an
individual item and can be
changed independently of
those around it. Art Works is
also a modular program, made
up of many smaller modules
which combine to form the
complete package. When run,
a control program loads in
each module from a special
directory and installs it within
the ArrWfliij environment.
STARTING UP
Like Impression, An Works
requires a dongle (a small
black box) to be fitted to the
parallel port of the machine
before it will operate. Much
has been said about the use of
dongles, both for and against,
but I think they are a good way
for software companies to pro-
tect against piracy - and they
do not really effect the user
once they arc in place.
Running ArtWorks produces
a start-up window displaying
the version number of the soft-
ware. A selection of icons then
appear in the window, signify-
ing which modules are being
loaded into Artworks, It is then
installed on to the icon bar,
A number of features from
impression 2 have been car-
ried over to ArtWorks. Any
number of pictures can be
loaded (or created) simultane-
ously, given that the host
computer has enough memory.
Different documents can be
viewed (if loaded) or removed
from ArtWorks as normal.
Also, different preferences can
be set up that affect the overall
use of the package. Selecting
The Mini tar shown on the previous page was
initially produced from a detailed tine drawing,
making the line tools one of the most important
parts of the entire Artworks package.
Three line tools are provided; straight, curved (or
beiier), and freehand. Users of Draw (myself
included) often take some actions for granted.
Artworks has been written to be as intuitive as
possible so there are a few bask changes that can
initially take some time to get used to. The Line
drawing tool, for example, only Joins points when
you click on a new point. There is no continuous
'rubber- banding' as in Draw, although lines can be
dragged around by holding down the select button
on the mouse whilst drawing. Filled objects can be
created by just dragging the start point of a line
over the end point whereby they ’snap" together.
Curved lines are created in a similar way to straight
lines: select a new point and Artworks will draw a
line between that and the last point. Like Bezier
lines in Draw, each point has two associated control
points which effect the shape of the curve.
Moving one of the control points will automati-
cally move the other in order to maintain the
roundness of the curve. 'Sharp" points can be made
by selecting a special corner option on the Info box.
Freehand lines can be drawn by just doodling with
the mouse as you would in a normal painting pack-
age. Artworks will then take the squiggle and
attempt to fit a curve along It, The level of accuracy
can be set with a slider control and the results are
impressive, especially with a fast Arm3 machine.

to customise it to the user's
requirements. You can drag
tools from the sub toolbox to
the main one, but dragging
tools from the latter removes
them and places them in the
appropriate sub-toolbox r
The info bar plays a less
active role, ft displays a con-
stant readout of the mouse
position (in millimetres) and
also the scale of the current
drawing, easily altered by typ-
ing in a new percentage .
However, two of An Works'
most useful features are con-
trolled from the info bar - the
undo/redo feature and the
Wysiwyg (what you see is
what you get) control.
Any operation can be
undone by clicking on the left
arrow or redone with the right
arrow, and it is even possible
to perform multiple undos to
take a drawing bock to the
beginning. The undo list is
saved with its associated draw-
ing. as part of an An Works
Hie. and will record all actions
required to create that particu-
lar illustration, Bui you can not
rely on it completely; there are
cases when it is impossible to
redo an undo, such as when
deleting a complex object. A
warning will be issued if you
attempt such an action.
The Wysiwyg control knob
allow s the level of rendering in
a picture to be set from simple
outlines to fully shaded
objects. The dial runs from one
to 11. one being outlines and
10 being fully filled in objects.
When set on II, all lines are
anti-aliased, producing a very
clear display in any 256-colour
mode, particularly when using
a multiscan monitor. Gener-
ally, the picture quality, even
in 16 colour modes, is excel-
lent, especially if the primary
palette feature is selected. This
sets (he desktop palette so that
a full colour spectrum con he
displayed using dithering,
Panning or scaling the main
window can take some time,
especially if you are working
on a complex drawing, so a
special button on the info bar
allows you to update the pic-
ture in the background,
IMAGE CREATION
So, how do you go about cre-
ating on image with ArtWorks?
Well, as we said earlier, this is
an object-based application,
and there are only two basic
objects in A rf Works - lines
and shapes. A line is just like a
path in Draw and consists of a
number of points with a start
and end. while a shape is any
line that has its start and end
points joined together.
Pictures can then be built
up by drawing lines and
shapes of any colour together
and then editing each object
until you like the results. The
tools used to build up a picture
can be split into two categories
- those that create objects, and
those that change or manipu-
late objects in some way.
These tools deal w ith different
aspects, including lines, shape
colours, and other useful fea-
tures, such as zoom,
TEXT
All text is stored in modular
form, in keeping with the rest
of ArtWorks and is regarded
by the program as a shape (or

ZOOMING IN
One of the most impressive Art- Here we have zoomed in on the
Work tools is the magnifying glass tax disc of our original Mini
used to zoom into the entire pic- (which fust happens to be out of
ture or selected parts of a picture, date - tut, tut!)
shapes). This means that text

shaded and can still be edited
at all times. A new Font Mana-
ger is provided with Art Works
to allow r rotated text, even in
Rise OS 2. Text files can also
be loaded in and edited, even
Although not available as yet,
it will also be possible to have
text squashed into envelopes
(see section on moving) and
still be able to edit it.
The caret will even change
shape according its wher-
eabouts on a line,
SHAPES AND FILLS
Three shape tools give
ellipses, rectangles and rectan-
gles with curved corners. All
three tools can be 'restrained'
(by holding down the CTRL key
on the keyboard) to produce
regular shapes, such as circles,
squares and rounded squares.
The CTRL key is also used
when another sort of locking'
action is required; namely
scaling and rotation.
But one of the most impres-
sive features of A rt is
the graduated fill. In Draw, if
you wish to shade' objects, a
number of multiple objects
have to be overlapped and
coloured to fit the required
scale. While Draw Eels you do
this automatically in Rise OS 3
the resulting file is large and
awkward to edit. In An Works.
however, you merely specify a
start and end point, and the
two colours to fill between,
and - hey presto - there it is
(see picture above).
Fills are stored as just those
items, thus saving a great deal
of memory. Another advantage
of ArtWorks is that they are
shown as one smooth gradua-
tion, using ArtWorks' ow r n
special dithering routine,
COLOUR
Because An Works is a 24- bit.
full-colour illustration tool,
likely to be used up to profes-
sional level, a lot of care has
gone into colour selection and
the provision of a wide range
of colours (shown left). Select-
ing colours for filling is simple
and is done in much the same
way as selecting styles in
Impression 2. A basic list of
shades is always available -
eight greys and eight colours.
The list can be added to by
selecting a current colour and
altering it using one of three
techniques'. RGB. HSV and
CMYK. RGB (red. green and
BBC ACORN USER APRIL 1992 91
GRAPHICS
The envelope too! allows for some highly versatile shaping
blue) is the method used in the
Rise OS palette utility. HSV is
hue, saturation and value, hue
being the general colour from
i he spectrum, saturation the
strength of the colour and
value the level of black within
the colour.
CMYK is a special method
commonly used in printing and
refers to the amount of cyan,
magenta and ye I low i nk
required for each dot in a pic-
ture. The K stands for key and
is the level of black needed,
MOVING
Any hne or shape can be
rotated or scaled around a
movable point. The Ctrl key
can be used to fix rotation to
steps of any predefined angle
or to force objects to scale in
both widih and length.
Those w ho have used pro-
grams such as DmwBender
and BBC Acorn User's very
own Snetch program, will be
familiar with the effects of the
envelope look Rather than try
to explain it. take a look at
picture opposite which show's
our familiar HA U logo, before
and after stretching, using the
envelope shown. By moving
the control points on the
envelope, any object within it
can be stretched or squashed,
The perspective tool can
also alter the shape of an
object by dragging the points
on to a quadrilateral, surround-
ing the object. The resulting
picture is shown in true per*
speclivc, instead of being
merely squashed,
THE COMPETITION
So how r does AriWorks com-
pare with the design giants
such as Cord Dime on the PC
and Aldus! Freehand or Adobe
illustrator on the Apple Mac.
Firstly, a number of things
are very similar, such as the
fountain fills from Corel
Draw, plus the ability to
import files from I he three pro-
grams above. This means that
Artworks has an immediate
picture library. Loading a
Corel Draw file is just a case
of using a PC disc reader
(already present in the new'
A50G0) and dragging it in.
Users of illustration pro-
grams on the PC and Mae
should have no trouble getting
to grips with ArtWorks - once
they become familiar with
Rise OS. Computer Concepts
has made the transition easier
by Including a utility, FltpTop*
which allows you to change
mode by just selecting the
resolution and number of
colours needed.
Where ArtWorks goes fur-
ther is in its capacity to exploit
the advanced features of the
Archimedes, which makes it
incredibly fast to use. Timings
made, comparing programs
such as Corel Draw running
on 486- based PCs with Art-
Works running on an Arc with
an Arm3 processor, showed
that a typical redraw speed
w r as up to five times faster
with A tt Works.
THE FUTURE
Because ArtWorks is modular
in design, tools can be
removed or added to the pro-
gram. This means that in die
future, it will only he neces-
sary to add or replace existing
modules if you want an
updated version of ArtWorks.
Computer Concepts is hop-
ing that third-parties will
design iheir own ArtWorks
modules and a reference
manual will be available for
those wishing to do so.
A typical example of an
later addition would be. say. a
graph module that could then,
in turn, make use of ArtWorks?
existing fountain fill and per-
spective tools. The list of
possible add-ons is virtually
unlimited and I can imagine a
whole flood of them just as
soon as the main program has
sold a few copies.
In addition to the features
outlined (no pun intended) it
will also allow text to be typed
around a curve, real-time in-
betweening from one object to
another, a grid facility for
accurate drawing and smart-
duplicate feature to allow rep-
eated patterns to be created
simply.
CONCLUSION
Although they both operate as
object orientated graphics
packages, comparing Art-
works with Draw is rather like
comparing Impression with
View (on the BBC Master),
Both do basically the same
thing, hut the former appli-
cation is the only choice if you
want high-quality output.
Many effects that would
lake a long time to produce in
Draw can be achieved in sec-
onds w'itb An Works, The
overall speed and friendliness
of ArtWorks makes it possible
to experiment with ideas, thus
aiding productivity. Given
time, patience and a little bit of
artistic skill, the results can be
astounding, as some of the
examples here demonstrate.
With the addition of Com-
puter Concept's Colour Direct
printer (see this month's
Graphics page) it forms what
is perhaps the easiest to use,
but most advanced graphic
illustration package, on any
personal computer today.
ArjHVjj-jfc.v should he out by
late spring and. despite being
aimed at the professional user.
I can see it becoming as popu-
lar as Impress ton is today.

BACKING UP
Making backups
doesn't have to be
a tiresome chore.
GRAHAM BELL
looks at a
simple solution
GETTING YOUR
BACKUP
A full backup of pre-selected files on to floppy discs
he essential problem with
backup software 3s that it is
less entertaining than play-
ing games - so playing a game
always seems a better way to
spend that spare hour. Even
the tiniest nuisance factor in
the program will seem like a
major fault. And, unless you
make backing-up part of your
daily or weekly routine, then it
wii! probably never get done.
Beebug*s Hard Disc Com-
panion aims to make the
process more palatable and
version two improves on and
tidies up on a lot of the loose
ends In version one.
Backup is the usual icon bar
application. It opens a simple
dialogue showing the current
choices: the main directory to
backup, the place to back it up
to and so on, A menu allows
you to choose between a full
backup, or two types of partial
backup. A differential backup
is every File that has been
changed since the last full
backup, whereas the incremen-
tal type is everything since the
last backup.
WAYS AND MEANS
The best way to use this
system is to do lull backups
regularly and then do differen-
tial backups every day. That
way, two sets of discs are all
that is ever needed to restore
your work.
Specifying the backup des-
tination is a simple matter of
dragging a directory icon to
wherever you want to put your
archive (on another hard disc*
say). Or you can choose the
default, ADFS::G.$, to put it ail
on floppies. In contrast, choos-
ing which source to hack up is
completely coun ter-i ntui tive:
you drag an icon from the
Backup window into the direc-
tory you want to back up,
rather than dragging the direc-
tories into the Backup win-
dow. However, there is a
flexible way of choosing
individual directories and files
to back up by dragging them
into a window^, and a way of
excluding Files and directories
by name or even by filetype.
Once you have chosen your
source and destination, you
can save your choices as a sort
of script file - double-clicking
on that file in future will repeat
the same backup procedure.
This is good for formalising
the full/di fTercntial routine:
you could keep two script files
called Day and Week,
As the archive is created, it
prompts for new floppies to he
inserted and it names the discs
in numerical order, formatting
them as w r ell* if necessary. It’s
reliable and you can pause at
any lime to do something else,
or even carry on typing in a
w r ordprocessor - it works
pretty much in the back-
ground, There's no problem
with long flies: they are com-
pressed and, if they are still
too long to fit on a single disc,
they are split. Compression is
much improved: version one
contained a short list of filet-
ypes which it would compress,
and few people bothered to
add to the list. Version two
tries to compress almost every-
thing except very short files.
And you can tune it (by editing
the Messages file) to try harder
if you have an Arm3.
How much compression is
achieved varies immensely: a
typical mix of data files com-
pressed to about 55 percent of
its original size, but a 2,5Mb
Impression document with lots
of sprites reduces to 13 per-
cent, Despite the compression*
be ready with about SO flop-
pies to fully back up your
1 00Mb hard disc * and put
aside a couple of hours.
The archives that Backup
version two creates are self-
extracting to an extent - it puts
Restore and Retrieve appli-
cations into the archive, along
with the data, so you can
always get your stuff back,
even if your only copy of
Restore w r as on your crashed
hand disc. Unlike version one.
Restore can only be used to get
back the entire collection of
Files. Retrieve is the new appli-
cation to gel back selected
files - but you have to remem-
ber the Filenames. There's a
wildcard search tor filenames
in an archive, but if you have
to browse, you too often get
the error "window full' when
you can't quite remember
enough of the name. Also you
cannot search for a file of a
particular type.
If you do find the file, then
you just drag it out to retrieve
it, but it would be better if
Retrieve showed a tree view of
the files and directories in the
archive and allowed you to
select both individual files and
whole branches of the tree,
like the old Mitre Disctree.
It is also worth noting that
some applications* notably
Beebug’s own Ovation.* cannot
be run from a restored copy.
CONCLUSION
Overall, Hard Disc Compan-
ion is a good but not a great
backup system. It’s convenient
to use* with fewer rough edges
than version one, better treat-
ment of new filing systems
and belter compression: a
worthwhile upgrade. Unlike
Spark, it splits long archives
over several discs, ifs faster
and it compresses practically
as well. But it still isn’t per-
fect* particularly for network
fileservers. where a tape
system is better.

MULTIMEDIA
ACTION REPLAY
PAUL JAMES examines the new full motion video system from Acorn
Acorn Replay - full-motion video capability on the Archimedes
Q he Hitchhikers Guide to the
Galaxy, that renowned
book, radio and television
series, provides what is pro-
bably the most famous exam-
ple of where multi media could
go in the future.
It featured a hand-held com-
puter which knew absolutely
everything about the universe
and was frequently consulted
by Ford Pie feet on his travels
through space and time. Ford
would ask the computer a
question and the little elec-
tronic book would launch into
a narrated, animated sequence,
to throw' light on to the subject
in question.
Today, the race is on in the
computer world to turn massed
information into a kind of
'virtual reality’, with particular
emphasis on moving video
images. Now Acorn has joined
the fray with its new full
motion video system - Acorn
Replay, Aimed primarily at
deve topers, it will undoubtedly
hasten the impact of multi-
media in the Acorn market.
DATA HANDLING
Until now the major hurdle
when using motion video has
been the sheer size of the files
involved. It is not just a case of
saving one Image, but a whole
sequence. The storage and
loading of such sequences are
the biggest problems, hut
Replay tackles both by using
existing hardware and some
very clever software.
CD -Rom systems can store
targe amounts of data. Just one
plastic compact disc can hold
around 96,000 pages of text -
anti that’s before compression,
which can iei some cases,
reduce the size of a chunk of
data by 20 times or more.
An increasing amount of
data is being transferred on to
CD- Rom format. Encyclo-
pedias, newspapers, reference
manuals and books (including
the Bible) are now being
turned into data which can he
read by the computer, decom-
pressed and finally shown on
the screen.
But until recently. CD-Ront
players have not been able to
produce moving picture
sequences on the computer
screen because of their inher-
ent slowness. A decent -si zed
picture - say. a quarter of a
mode 1 5 screen - consists of
around 40Kb of data. To get
the 12.5 fps (frames per sec-
ond) needed to fool the human
eye into seeing a fairly
smooth-running image, the
computer needs to suck about
4,096,000 ones and zeros from
the player per second. With
current mainstream hardware,
that is just not possible.
However, if each video
frame is compressed, then it is
possible to get 12.5 frames of
data per second from a CD
(25 fps from a quicker device,
such as a hard disc). The com-
puter then has to decompress
this data and place it on to the
screen - no mean feat.
This is w'hut Acorn Replay
achieves. With a standard
hardware device (either a CD-
Rom or a hard disc) containing
the movie file, the decompres-
sion and display can be han-
dled by the Replay software.
The fact that no special hard-
ware is needed is what makes
Rep tax so cost effective, com-
pared with other hardware -
based solutions.
The compression techniques
are the key lo the Replay
system, (see box) making it
possible to Jit a 1 2 sec, 1 2. 5 fps
film on to a single floppy disc.
Acorn has also thrown in mul-
tiple channel, stereo sound,
CONCLUSION
Acorn Replay opens up new
multimedia options, Moving
pictures are instantly impres-
sive and guaranteed lo grab
attention. Used in the right
circumstances, they are far
more informative than text,
one example being a short
movie showing how to operate
a piece of equipment. An
A 5000 with a built-in video
tutor? Well, memory would be
a problem, but it is possible.
Although Replay is not
aimed at individuals (the
Archimedes system needed lo
make the sequences has to be
powerful and requires expen-
sive additional hardware), it is
sure to be picked tip by soft-
ware developers who, by
incorporating the compression
and decompression facilities,
will be able to include moving
pictures in their own packages.
Support for Replay has
already been included in the
Magpie and Genesis multi-
media packages. Before long,
we could see many appli-
cations, released on CD- Rom.

Acorn Replay is primarily aimed at software developers, The sequence, in
the form of a video or similar media, is passed on to a company who will
then master it and put it on to a large storage device, uncompressed. The
first part of the Replay software then comes into play.
First, the video data is reduced to Archimedes' sprite format, then
each frame is taken in turn and compressed. At this stage r the compres-
sion is simply a case of removing data from the image - and it is no loss,
since this is data that the human eye is unable to see anyway. Areas
which include several, subtly different colours are evened out, and
highly detailed areas are smudged Then a form of Delta compression is
used, which relies on the fact that only one part of the picture is moving,
while the rest is stationary. As the computer already has the data for the
stationary part, it doesn't need it again, so this is disposed of.
Finally, the finished ArmMovie file is placed on to the hard disc or
mastered on to a CD-Rom. This method allows about 6Mb of film in
Archimedes format (this would be far bigger in original video format) to
be compressed down to fit on to one 35in floppy disc (about SOOK). This
is worth I2sec of 12-Sfps video.

LOOKING AT
THE FAX
With the Archimedes attracting increasing interest from business users,
GRAHAM BELL looks at a package which can turn your Arc into a fax machine
B ne of the icons of modem
technology is the facsimile
machine. The need for fast
communication means faxes
are now found in most offices.
Combining fax and compu-
ter technology makes sense -
in principle, a Archimedes
with a printer, scanner and
modem can operate as a com-
puter system, photocopier or
tax machine. Add a sound
start pier and you have an ans-
wering machine too,
FtiXPack from Computer
Concepts is a fax expansion
hoard which turns your
Archimedes/ BBC A3000 into
a fax terminal. Et first appeared
some years ago. hut it fell foul
of problems with Arthur, the
original operating system for
the Archimedes, and was with-
drawn. With the advent of Rise
OS plus the IRQutitx and
Hourglass modules, these
problems have been solved.
Fax chip technology has also
advanced greatly, so CC has
re-do signed the product.
The new package comes in
the form of some software,
plus a half- width podulc which
slots into the back of the
Archimedes and connects with
a phone line. Fitting to the Arc
easy enough, but you do have
to he careful with a tiny ribbon
HOW FAXES WORK
Faxes have much in common with familiar computer
peripheral*. A conventional fax machine is little more
than a specialised 9600 baud modem teamed with an
A4-width scanner and printer. The scanner scans the
document, and the image data is transferred to the
modem and on to another fax machine, where it is
printed. In fact, the image is compressed before
transmission, so it takes less time to transfer the data
for each page.
Most modern fax machines are known as 'group V r
which means that the scanner and printer work at up
to 200 dots per inch - about dot-matrix printer qual-
ity. But the majority of machines have normal 1 and
'fine' scanning modes, normal being quicker because
it is only 100dpi. Combined with imperfections in the
scanning and crackly phone lines, it means that most
faxed documents are of questionable quality.
To boost the quality on poor phone connections,
most group 3 machines step down from 9600 baud to
7209, 4800 or even as slow as 24Q0baud. But there is

APPLICATIONS
Once set up, there are two
applications to be copied from
the software disc: the a normal
printer driver, PrinterFP, and
second Faxmngr. used lor con-
figuration of FaxPack and lor
fax reception, h is separated
from PrinterFP so that you can
still receive faxes when you
load another printer driver -
perhaps to print out a previous
fax, for example.
Configuration is mostly a
matter of selecting yes or no
from a list of options - for
example, whether to use
[ouchlone dialling fif you ate
attached to a modern digital
telephone exchange), or slick
to old-fashioned pulse dialling.
You should also enter your
own telephone number. Fax
machines identify themselves
to each other, and your number
will show up on the machine at
the other end.
Sending your first fax is
almost as simple as printing.
You need both Faxmngr and
PrinterFP on the icon bar, then
you enter the destination fax
number in a dialogue box and
choose print from any appli-
cation that uses the Rise OS

BUSINESS
The FaxPack half-width podule connects the Arc with a phone line
primer drivers - Edit, for
example. When you print.
Fax Pack assembles die page
in memory in seconds, then
dials the number. If it connects
to a suitable lax machine ill the
other end, it sends your docu-
ment. Von get control of the
computer back as soon as it is
assembled - the lax data is
transmitted in the background,
and even on an Arm 2 machine,
it is barely noticeable.
The sounds made during
dialling and sending of the
data are important, since with-
out sound you don't get any
indication of what happening
your fax just goes. IF it foils to,
because the receiving machine
is engaged or won't answer, an
error box pops up on the
screen. Unfortunately, there is
no sound on the A30QG,
BETTER QUALITY
Faxes received from Fax Pack
look much better than from
most dedicated fax machines;
straight lines no nasty streaks
etc. With conventional faxes,
most errors occur at the scan-
ning stage (which FaxPack
avoids) rather than in transmis-
sion or printing. After trans-
mission over normal telephone
lines, even six-point text (this
is nine-point) is readable.
However, it is worth turning
the Quick text option off. This
is Computer Concepts’
replacement for Acorn’s font
module, used in both Fax Pack
and the Lascrdireci prin lei's.
Although it works well on a
Luserdirecl printer, where the
resolution is 300dpi (dots per
inch) or greater, at Fax Pack's
3(M)dpi it tends to miss out
pixels in thin horizontal curves
- die tops of the ’c\ lor exam-
ple. Although it is slightly
slower. Acorn's font rasle riser
draws skeleton lines through
these curves to make sure the
tellers are continuous. Quick-
text ignores the skeleton lines
and leaves gaps where the out-
line is thin.
Fax Pack adds a page num-
ber to the top of each page,
and can include a running
header. It slightly distorts the
document, making it a bit nar-
rower and longer than a "true
si/e' primer, but this isn't
really a problem because of
the informal nature of fax
co m mu n icatt on s . Howe ver,
stick to A4-si/c paper and he
generous with the page m sir-
gins when setting up a docu-
ment. as there can be no
indication after you've sent a
document that it will be com-
pletely legible at the other end
The final software was not
available for this preview, and
certain features destined for
the release version were miss-
ing. For example, if you forget
to enter the destination fax
number in the PrinterFP
dialogue box, it pops up an
error box when you 'print’.
The final software will pop up
a box requesting the number to
dial - much belter. It would be
even better to he able to drop a
text tile containing solely the
fax number on the printer
driver icon - for example by
dragging a field out of a Squir-
rel or another database.
Other untested features of
the software include keeping a
log of fax traffic, and the
i n tended FaxPack-Xo-F axPack
file transfer, enabling a file or
whole directory to be trans-
ferred between FaxPack-
equipped machines - you will
be able to just drag the file or
folder on to the PrinterFP icon.
RECEIVING YOU
Setting the Fax Pack up for
reception is quite straightfor-
ward, You need to set up a
directory to receive fax files
into, and you need to be run-
ning the Faxmngr application,
lust how you do this varies; if
you are blessed with two tele-
phone lines, one can be dedi-
cated to fax traffic, and you
can set Fax Pack to auto-ans-
wer. For a more normal setup,
where Fax Pack has to share a
line with ordinary telephone
conversations, you can't have
Fax Pack answering all your
calls with its ear-piercing
whistle. You can set it to
manual answering, then
whenever you pick up the
phone and you hear a fax lone
from the other end, you use the
Faxmngr menu option to begin
reception. During reception
you can continue with
something else, since it all
happens in the background and
won't disturb normal w ork.
The quality is not as impres-
sive as faxes you send,
although it depends on how
good the fax machine is at the
other end. But you can read
fax files simply by clicking on
them The leading application
is simple, with tittle more than
a page up/page down interlace.
It would benefit from an
option to rotate from landscape
to portrait, but it is easy to
print or read the fax 011 -screen,
crop out a section, or save it as
a sprite. The latter option docs
have problems though, as the
sprite files do not work
directly with Paine
You also need to clear out
your fax directory fairly fre-
quently, as each page lakes up
to about 1 50Kb of disc space -
don't consider FaxPack unless
you have a hard disc.
CONCLUSION
For business users, who may
be judged on the speed and
quality of their output, or for
genera! users who want to
communicate with each other,
FaxPack offers solutions. You
can use it with almost any
printer driver-aware appli-
cation, and most of the others
would work with the supplied
LQe mulale application that
can make FaxPack appear like
an Epson dot-matrix printer.
FaxPack works well, offers
impressive results and repre-
sents exceptional value.

FAXPACK SMART CARD
The FaxPack podule is one of only a few Archimedes expansion cards
provided with its own intelligence. As well as the dedicated fax modem
chip that handles the telephone line, there's an 8931 8-bit microprocessor
that does most of the work. It only interrupts the Arm chip to transfer
chunks of data to or from the dual-port Ram on the podule - a simpler
board would use the Arm to transfer individual bytes of data and to
control the fax chip directly .
The PrinterFP software shares many features with the Userdirect, and it
first assembles the page in a compressed form in the Archimedes memory.
You can configure the amount of memory used and r because of the lower
200dpi resolution of fax, it doesn't need to be a big buffer; 512k is ample.
The current versions of PrinterFP and the Laserdisc? drivers share a
serious problem when printing out from Squirrel: text fields consisting of
more than one line of text can't be printed - a huge black block is all that
appears on paper. However, this isn't a problem with any other appli-
cations, and text, sprites and drawings are ail correctly incorporated into
your faxes.
Future software upgrades intended for the FaxPack (and for Laserdirect)
include a networkable version which splits the printer driver in two - half
at your workstation, half at a 'fax server 1 on the network. The communi-
cation between the two is at Draw-command level: this should clog the
network much less than Oak Solutions' current networked version of the
Laserdirect driver which transmits the compressed bit-map of the entire
page over the net, and should allow printer messages to be routed back to
the correct workstation.

PUBLIC DOMAIN
I jJ ncc software - sounds too
r" ■ good lo be true, doesni it?
Well, that is exactly what
Public Domain (PD) software
is all about.
In the earlier days of Beeh
computing. PD grew mainly
from the programming arena.
Enthusiastic home users wrote
simple programs to solve
specific problems then these
solutions were shared out
among other users
Over the years these
'freebie' programs have
become known as Public
Domain (PD), which means
that you can copy and distrib-
ute the programs, usually
within a set of basic ground
Riles, such as not altering the
program files or code, leaving
the author's name intact and
not making any commercial
profit from distribution.
The past lew veal's have
seen a steady build-up of PD
program titles for the Acorn
range of computers. Some
have evolved to such an extent
that they now rival commercial
software products and repre-
sent excellent value for
money, usually only costing
the price of a disc and postage.
At this point. I should point
out the difference between PD
software and shareware soft-
ware, over which there has
been some confusion in recent
months. Whereas PD software
is free to copy, use and pass
around, shareware software is
free to copy and use only for a
limited period.
However, if you use share-
ware software continuously u
is customary to send the author
a donation. This in turn gives
the author incentive to produce
more programs in the future.
Some authors will also send
you updated versions, or even
a manual, if they receive such
a donation.
EASY ACCESS
There arc numerous ways to
get hold of PD software. The
easiest is probably by brows-
ing through the Software
Showcase pages at the buck of
BBC Acorn User, where
advertisements can lx 1 found
for a handful of PD libraries,
Most have a demonstration
disc i hat gives a rough indi-
cation of what software range
they supply, and you can
usually buy the demo for a
pound or two.
Another way of obtaining PD
software, if you have access to
a modem, is via one of the
various bulletin boards, which
often contain many megabytes
of software that you can down-
load for the cost of a telephone
call. However, if you are
downloading, check the length
of the software before you
start - it can cost more to
download a program, in terms
of telephone charges, than to
send off for a disc,
Another thing to bear in
mind when obtaining PD soft-
ware is the spread of viruses.
Luckily, most PD libraries tire
fairly diligent and. personally,
I have never found a virus on
any PD discs. Bulletin boards
are perhaps more likely to be
infected, but again, most
Sysops (system operators)
regularly check their down-
loads for infection. If in doubt,
obtain a virus checker which
many PD libraries can supply.
As PD software covers prac-
tically any subject you can
think of, we can really only
give you a taste of what is
around. Here is a selection of
some of the more impressive
titles - if you arc a subscriber,
all of these can be found on
our BA U subscribers' disc, but
you can also obtain them
directly from the PD distribu-
tors - sec our Where to Go
box for more details.

KEEPING TRACK
• ProTrack -Soundtracker player routine
• Ail Archimedes machine's
• Arcaynia PD (written by Gass)
One of the more prolific areas of PD is the range of demos and sound-
tracker tunes available, many ported from other computers, such as the
Amiga. Hugo Fiennes wrote the first Archimedes program to playback
tunes from Amiga SoundTracker, a program which over the years has
been extended and modified to become a slick and professional-looking
program, ProTrack has been produced by the Belgian Archimedes
Software writers. Society, and is an impressive addition to any PD
collection. Running from the desktop and totally Rise OS compliant,
ProTrack will play any tracker tune, as well as provide you with a range
of control panels enabling you to examine and control the tune in more
detail. Four panels are provided: a control panel which lets you fast
forward, play, rewind, stop or pause the tune currently being played: an
enquiry window, which allows you to examine more specific details such
as the tune length, number of samples used, memory size and effects
used; a monitor screen, which lets you see the actual tracker data and
musical waveforms, together with a spectrum analyser type display, all
updated in realtime as the music plays; and finally, a preferences
window, which lets you alter the stereo position of each channel playing.
Pleasant 3D icons have been used throughout the overall package.

INTELLIGENT ANAGRAMS
• SuperGram - Inte-tligent Anagram finder
• All Archimedes machines
• The Datafile (written by William Tunstall-Pedoe)
Supergram is not a run-of-the-mill anagram solver. Indeed, if simple,
single word anagrams are what you're looking for r a word processor
spellchecker will do. Where Supergram excels is in creating multi-word,
intelligent anagrams horn phrases and sentences. In fact, you can
customise it to put varying degrees of emphasise on its weighting so
that you can create satirical, flattering, political or even rude sentences.
It is a fully Rise OS application, which is even multi-tasking so that you
can continue working while your computer shifts through hundreds of
words in the dictionary. All you have to supply is a simple phrase to form
anagrams from, set a few simple options such as what emphasis or bias
you want, click OK and off it goes.
After a few minutes, a list of words Start to appear in a window.
Being multitasking, you can watch as it sorts out the best ones chosen so
far. After a few moments you can peruse through pages of most
amusing anecdotes. Supergram has a good knack of being able to sort
words according to context, so that they can have a subtle way of
Sinking with the original text. For example 'I am plastic' is one of the
anagrams produced from the source word 'capitalism', while 'Rise
workstation' produces 'it is star crown OK'.
Many hours of fun can be had by compiling insults from peoples
names, answers to questions or thinking up puzzles to give to friends.
Supergram just goes to show how professional looking Public Domain
programs can be.

the form of multiple choice
questions, based upon the sort
of accident you may witness in
real life. Each question moves
on from previous actions and
responses, giving you lull
instructions and a tutorial if
you choose die wrong answer.
It also helps by explaining
why you went wrong* rather
than just scoring a negative
mark. This can help people
learn by their mistakes and
show you how a chain of

Considering the sound abilities

quite impressive.
BDARK
BBC Model B/M aster
Digital Phenomena
Due to the large amount of
memory used by many Archi-
medes programs* the archiving
of programs is often called lor.
Archiving essentially involves
reading a file and com pressing
it by eliminating consecutive
similar bytes. By compressing
files, you can greatly increase
the amount of data you can
store on a d i sc. somet i mes
increasing die capacity by two
or three times,
Et also allows you to store
multiple files within one file.
This can help people down-
loading from bulletin boards,
who only need to download
one file rather than lots of little
ones. Although the BBC micro
has a much smaller memory
than the Archimedes* there are
still limes when archiving pro-
grams can be beneficial, such
as when cramming more data
on to a disc,
Bdark will allow you to
extract files that have been
archived using Spark on the
Archimedes. This is the
accepted standard so far and
allows Arc users to compress
files for transferring to the
Beeb, Using it is fairly simple
- you simply copy Bdark and
die file to be de-com pressed
on to a blank disc, and then
type BDARK <filename> where
filename is the name of the file
to be decompressed. The I lies
will then be unsquashed and
saved on the disc, so you can
run the program as normal.

GAME SHOW
Watch out for the Archimedes version of The Last Ninja, from Superior
E his month there is ji snippet
of very welcome news for
any gamesters who have
recently acquired the latest
jewel in the Acorn crown, the
Archimedes A50O0.
The Fourth Dimension* one
of the leading software houses
in the Acorn games market,
has come up with a solution
for anyone who may have
experienced difficulties when
playing games on the new
machine. The A 5000 has a
newly-designed Rise OS 3
operating system, which is
slightly different to the Rise
OS 2 system found in other
Archimedes and BBC A 3000
machines. This has been caus-
ing a few problems with
certain games which do not
seem to work properly.
As a result, the Fourth
Dimension tweaked some of
the games in its range and
reports that they now work
perfectly on nil of the Rise OS
machines* The company is
offering a free disc replace-
ment service for any users who
have Rise OS 2 versions. All
you have to do is send back
your discs - keep the box and
manual - to The Fourth
Dimension, 1 Percy Street,
Sheffield S3 8AU, with a short
note requesting the upgrade.
Meanwhile* the sequel to
The Fourth Dimension's Afcv-
ryori - 'imaginatively called
Nevryon 2\ to quote the
author - will be released this
summer. But. you may well
ask, what could possibly be
added to the original game,
given that it was already as
busy as a bustling beehive.
Well, the short and simple
answer is this. Two people will
now be able to play simultane-
ously. blasting yet more
nasties from space ships and
Hying along horizontally,
shooting and collecting
bonuses, as in the original. The
play area will also be enlarged
vertically to make room for
even more flying objects lor
you to eliminate.
My one plea to The Fourth
Dimension is this: when you
ion out of lives in the new ver-
sion, please could you design
it so that it is possible to start
playing again straight away. In
the original Nevryon you had
to wait nearly two minutes
while high score charts, wig-
gly graphics and flashy titles
rolled by,
BRIDGE TOO FAR
Any bridge players out there?
Well, you will be pleased to
know that Krisalis Software
intends to release an Acorn
version of its new game Omar
Sharif's Bridge, in an effort to
take the company upmarket.
Krisalis’ Tony Kavanagh
told us that the game had gone
down a storm in the L’SA and
he wants British players to
have an opportunity to get
involved. And you never
know, it may encourage many
more people to start playing
this fascinating game - in fact,
! might even learn how to play
it myself!
A completely new game to
the Acorn world, also on its
way from Krisalis, is the
highly successful game Popu-
lous* which has gathered wide
acclaim on other computer
formats, especially Amiga.
The game won't be out until
later in the year - watch this
space for more details.
Meanwhile, you might be
interested in a little statistic
regarding Acorn's growth in
the games world. Krisalis
reports that it sold over a 1QOO
more copies of its game Mad
Professor Marian I for Rise
OS machines than it did for (he
Atari ST, once a computer to
be reckoned with on (he games
scene - she best will always
out!
CHEATING
A nice little cheat program to
make life easier for players of
the adventure game. Twin
World* has been sent in by
Stephen Cook of Edinburgh,
The program {see light)
enables you to alter the saved
position 11 le to make you start
on any level, between /cm and
22, And although u is possible
to change other factors, such
as the score and weapons.
Stephen has deliberately left
these out of his program to
maintain some element of fun
in the game [although [here is
no reason why ihe hackers
among you can't put them in ).
To use the cheat, play Twin
World and save your position,
l hen gel into Basic, To do this
from the desktop* press FI2
and type basic. Then enter the
program as it appears here and
save it to the Twin World disc
by typing ° ADKS then
savk'CheaT" before typing
run lo begin cheating! Thanks
to Stephen for that.
Another tip for cheating at
The Fourth Dimension’s
shoot- 'em -up. Apmnlypse* has
been sent in by Robert Miles
of Homerton. Devon. In Apo-
calypse you fly around a
brilliantly coloured planet,
firing yellow photons from
your Hying saucer at various
targets below. 1 think they're
supposed lo he the bad guys,
although the other saucers
are n't particularly neighbourly
either. To use the built in
cheat, just type in ELIZA, while
on the surface of any planet, to
go to any level,

Do you remember the Eilien out
of A Hat - tali, multi-] imbed
and ugly, with that big shiny
shell thingy on its back? Well,
some of the creatures in
Aggressor - all wearing a sin-
ister purple exoskeleton - are
she spitting image of the old
beast ie (whom we have named
Egor), only here; they dash
about in search of trouble with
all the grace and coordination
of an American Football
player. So what do you do
with them? Well... shoot 'em,
of course!
But no sooner has the Egor
hit the ground than you have
something else to deal with,
typically an oversized pink
cockroach with an altitude
problem, a hyperactive blue
monkey with a bee under its
bonnet, or tin u na f feet tony te
swarm of bees with a chips on
their shoulders, Plan of action

And that's about the extent
SWIV
Krysalis Software
Tel: (0709) 372290
Price: £24*95 i«c vat
Krysalis continues its tradition
of bringing the best games to
the BB C A30£)Q/Arc hi modes
by releasing its latest offering,
5wrr. Hailed by many as the
best shoot-em up available for
any computer, be it eight or
16-bit. Swiv is a a real arcade
game in every way.
Set in the not too distant
future, Swiv puls you in charge
of two vehicles, a helicopter
and a jeep. Both are armed for
combat and have I heir own
particular uses. The jeep is
land-based and dodges behind
buildings to avoid enemy fire,
while the helicopter flies
around the whole play area.
Both vehicles can be con-
trolled simultaneously using
the keyboard or joystick.
When both the jeep and heli-
copter are used, it is best to
have two players controlling
i he movement. It's not really
of the game; definitely in the
if it moves shoot it’ category .
li is set sometime in the future,
somewhere in space and fea-
tures a couple of hand nuts
named Heckler and Kosh in a
war against the weirdos.
Although it sounds like it
should be my kind of game
full of action, enhanced
weaponry availing collection
and best of all a two player
option somehow Aggtess&r
just doesn't make the grade.
The scenario scrolls horizon-
tally and Heckler. Kosh (or
both) have to amble along,
ducking and diving enemy fire
and even jumping over strange
holes in the ground;' popping
I he baddies and collecting
crates full of bonus gadgets
which float down under para-
chutes from time to time. The
graphics are actually fairly
good, but despite some nice
detail, they lose smoothness in
the heat of the action
The trouble is that the whole
game is rather too slow and
you gel about as much
response out of Heckler and
Kosh as you would from a
dead duck on a cardiac moni-
tor. Mot only do they tend to
ignore important signals like
slop tiring now please../ but
they can't run half as fast as
Egor, or the strange animals he
hangs about with, placing you
at a distinct disadvantage.
Also, in two player mode
you are both confined to (he
left half of the screen, which
causes severe annoyance when
the forward positioned player
has to wait for the lagging one
to catch up.
Basically, the game looks
and sounds good and has the
sort of mindless plot 1 seem to
like, but sadly the lack of
speed does destroy the fun.
Fast smooth action is the key
to any game of this sort and
lacking this makes Aggressor
seem like like a conceit with-
out a band or a football match
without the teams.
Sam t/rveniiill
lions to be loaded in while you
are playing, without any
apparent break in play.
Because there are no breaks,
the action is fast and furious
and just gets more intense the
further you progress. After
three lives have gone, a credit
feature (rather like stoking an
arcade game with lots of 20ps
before playing) allows you to
continue from where you die.
The graphics and sound are
well up to arcade standard,
perhaps not quite as last. Like
most of i he Krysalis games.
Swiv is a direct conversion of
the 16-bit version, with no use
made of the Archimedes'
superior sound and graphics
capabilities. It doesn't detract
from the game play, but more
colour would have been nice.
If you were to stick an
Archimedes playing Sn 7r in an
arcade, you could almost
believe it was the real thing.
So if you're fed up of spending
all that loose change? why
not invest in a copy of Swiv?

PROGRAMMING
mong the many attempts to
make Rise OS a friend tier
environment for program-
mers to work in, HelixBasic
from Craddock Computer
Systems is perhaps the most
imaginative. Although 1 say
new, it is still under develop-
ment, but [ have looked at a
pre-release version to see
whether progammers' lives are
about to be transformed.
APPROACH
BACK TO
BASICS
New software could make programming
tasks much easier. DAVE ACTON gives
some first impressions
HelixBasic provided a shortened program for this crossword designer
The traditional approach to
assisting application writers
has been to provide various
editors, procedure libraries and
so on. This is all very well, but
many Basic programmers sim-
ply want to be able to write a
short program and see it run-
ning in a window.
HelixBasic is actually a
Basic V interpreter (running
independently of the standard
Basic) which transparently
multi -tasks, running your pro-
gram in small ‘time slices'
while allowing other appli-
cations to run alongside it. In
this respect it is what many
programmers will want.
I wrote a short application in
HelixBasic - a crossword grid
designer - to see how well it
performed Although hindered
by some of the problems yet to
be ironed out, the program
certainly ended up much shor-
ter than the equivalent in
ordinary Basie. Some tasks,
particularly the displaying and
saving of the finished cross-
word grid as a Draw file, were
remarkably easy.
The standard Basic com-
mands are supported where
appropriate, but there are
many new ones that specifi-
cally deal with the desktop —
too many to describe in full,
but as an example I decided to
look at menus.
If you are building a menu
from scratch in a Basic appli-
cation you normally require a
set of functions and procedures
to create and interpret them.
Some programming aids allow
you to build menus as text
files, but this is often limiting
since menus arc at their best
when 'dynamic' - in other
words, options should ready
change (be ticked, greyed out
and so on) depending on the
circumstances. HelixBasic pro-
vides two keywords - MENU
and addmenu - that greatly
simplify the creation of menus,
while maintaining flexibility.
The main menu in my simple
application was set up with
just these commands:
MENU main_menu, H ‘Cro5sw&itf 1
ADDM ENU roatn_ii)enur5ave'’.SA VE
ADDM EN II ’“Clear
|rid'’,MENU c1ear_mi;nu
ADDMENU
dUiidnenu, M Word3 7 ',GREY
csji!_enter.MENU WG*tt_nai*iiu
The submenus ciear_nw:nu and
wor<Lmenu were defined else-
where. The keyword save
means a save box is brought
up and the last entry in the
menu is greyed out whenever
cant_ent« becomes true. This
illustrates an important feature
of Helix Basic - the ability to
link things to particular vari-
ables, so that any change in
their value is automatically
reflected elsewhere.
Another example is window
titles. These can be fixed, or
linked to variables so that
changing them can be as sim-
ple as tiXk$- H New title".
Similarly, commands can be
linked to particular actions, so
clicking on an icon or select-
ing a menu entry can be set up
to call a procedure, close a
window or whatever.
This may cause a few sur-
prises for newcomers to multi-
tasking who expect their pro-
grams to lie executed line-by-
line, It is a feature of Rise OS
(and not a limitation of Helix-
Basic) that you must beware
of events taking place in an
unexpected order.
GRAPHICS
Another key feature of Helix-
Basic is the way it treats
graphics. Outside the desktop,
when you draw a line on the
screen you expect it to stay
there. In a window, you may
not always be able to see it, so
your application needs to keep
track of lines, circles, text or
whatever so they can be
redrawn whenever necessary.
HelixBasic quite logically
stores all graphics as a sort of
internal Draw file. Indeed, you
can save the contents of a win-
dow as a Draw file with the
SAVEDRAW command.
This facility means that my
crossword designer simply had
to plot the grid with a couple
of for... next loops and a few
rectangle fills, and then the
finished product could be
saved directly into Draw.
Well, in fact a couple of the
teething problems got in the
way. In the pre-release ver-
sion, fonts and text were not
saved in the file and direct
a pp I ication-to -application sav-
ing was not supported, but
these will be featured in the
final version.
Although you can use Edit
(as I did) to create your pro-
grams, a new and faster editor
is promised, with y more
graphical approach to window^
design. Another area where
improvements are promised is
in error trapping - at present,
responses are far from ideal,
such as 'Abort on data trans-
fer' when you miss out the
keyword THEN.
Geoff Craddock of CCS told
me thal the full release version
of HelixBasic would be avail-
able this month and I look
forward to trying it. Whether
programs will run faster with
the new version is yet to be
seen - we may have to wait for
the HelixBasic compiler, due
later in the year,
CONCLUSION
The idea behind HelixBasic is
essentially a very good one.
Schools in particular will find
the simplicity appealing and.
with a compiler, a good
manual and a fast editor, many
programmers may be tempted.
Having said that, it will take
a fair bit of work to transform
the current development into a
finished product. If CCS man-
age it, then they might well
have a hit on their hands.

/ SmArt is a Linked Graphics System. When
jsHt picture files are loaded into smArt, different
parts of the picture can be changed by
making selections from a menu. The graphics components
are automatically scaled so that the parts always fit. Pictures
may be saved as Draw files or transferred to DTP programs
or any other applications which can handle Draw files.
The smArt package comes with over two dozen files on
subjects ranging from shops to cars, and churches to British
Isles maps. Available as separate products are discs of
smArt files on specific themes such as Leisure, He raid ry.
Faces, Fashion, Homes, Trees & Gardens, and Dinosaurs.
smArt £55 (NZ$ 1 98) smArt discs £1 6 (NZ$ 59)

For those wishing to create their own smArt
files, smArtFiler is an application which
compiles smArt fifes from your source Draw
files. Full instructions are provided along with lots of
examples. Individual components may be scaled, rotated,
and placed in front of or behind other components. Menu
entries may be specified.
If it can be drawn it can be a smArt file.
smArtFiler £35 (N2$ 129)
T Chameleon is an ideal companion to
MCJrgM&fcOJ? smArt, and a must for anyone who needs
to make quick and easy colour changes to
Draw files. As well as palettes for 16 and 256 colour modes,
there are options for 256 shades of grey and a RGB colour
cube which provides thousands of colours. Colours may be
selected from other Draw fifes so can be copied from one
picture to another. Colours may also be changed in HSV
values; Hue, Saturation and Value, Edited files may be
saved as normal Draw files or as colour separations A clever
Undo and Redo facility allows virtually any number of colour
changes to be cancelled and then reinstated. Zoom and
