From The Top; 

I would like to talk to all of the 
members about the support that the HAUG 
gives to the ATARI computer system line. 
The club supports two BBS, a monthly 
newsletter, the Public Library, both the 
8-bit and IB-bit computer systems and the 
IEEE Computer Fair. The club has donated 
to the Public Library, a 130XE system For 
general public use. The newsletter goes 
not only to the HAUG members but to many 
exchange ATARI Clubs in the USA and a few 
out side the USA. We bought a Full ST 
and hard disk system to use on the HAUG 
BBS. The controller card/assy and power 
supply for the Bloom County ST BBS was 
paid for by the HAUG. The phone bill for 
both of the BBSs are paid for by the HAUG 
also. The club has bought the full set 
of repair equipment for the S-8it 
Computer systems. The club can repair 
almost anything for the 8-bit computer 
system now. This is another service we 
offer to all the members of HAUG , 

As you can see, the club has put in 
a lot of effort on the total ATARI line . 
In the near future we will need to start 
getting all of the repair and test 
equipment for the IB-bit (ST) line. This 
will give us ( HAUG ] the edge up on most 
of the ether Users Groups around the 
states. We can keep the ATARI Computer 
in Huntsville alive and well. But to do 
this we will need to have more money. 
The Board of Directors would like for the 
Members to vote for a increase in the 
YEARLY DUES , The dues have been $12.00 
for a long time, I have been a member 
for about four years and it looks like 
for us to continue doing all the things 
we now do, we will need more money. The 
Board would like to raise the DUES to 
$15.00 a year. The cost of doing 
business is going up. The postage is up 
from three years ago , the phone line 
charges are up, and printing of the 


newsletter is going up. As you can see 
everything is going or has gone up except 
the money coming in. It has stayed the 
same for the last three or four years. 

The bottom line is YOU the members 
will need to give this some thought so we 
can talk and vote on this at the IB 
October meeting. If you would like to 


see more 

of 

an increase 

we will talk

also.

SOFTWARE BLACKOUT? 
by Bill Powell 

At the August H.A.U.G. meeting, I 
brought up the subject of Atari 8-bit 
availability - or more precisely - its 
non-availability. During the discussion, 
a comment was made by the news editor 
that Huntsville was a H Commode re town". 
And I can agree with that statement after 
searching through most of the stores 
around here looking for software. I T m 
also concerned because it seems that 
other cities are becoming just as void of 
new software for 8-bit machines. Cities 
like Madison, Montgomery, Mobile, 
Texarkana, Rock Island, Moline, 
Petersburg, Roanoke, Salt Lake City, and 
even Denver seem to suffer from the 
shortage. Are these cities also "just 
T Commodore towns" 1 ? 

I don’t know about you, but this 
writer has invested over $3000.00 in 
Atari equipment and software* I would 
hate to have to sell the whole bunch (and 
loose a bunch!) just so I could purchase 
a machine which has new and current 
state-of-the-art software available for 
it . 

I subscribe to Family Computing 
magazine. I used to see review after 
review of 8-bit programs - for the Atari. 
Lately, they have very few of these 
reviews. Most software is listed for the 
IBM, Apple, or Commodore machines. Yes, 
FC still provides Atari 8-bit program 
listings - perhaps in expectant sympathy 
for us Atari owners who might soon join 
the ranks of the Adam’s and the TI-99 f s. 

Newer, faster, better 8-bit software 
continues to be developed - but not for 
Atari machines , Wouldn't it be so simple 
to place the Atari version on the flip 


Page 1 


side of the IBM/ Apple/ Commodore disks? 

The software problem is mentioned by 
individuals now and then in various 
computer magazine "letters to the editor" 
columns, yet I believe we can provide a 
stronger influence to software companies 
through official club correspondence. 
The club secretary tells me there are 
plenty of us still bootin' and printin' 
on these Atari's, You can help solve the 
software "blackout". Bring your 

convictions, desires, and a pencil to the 
next H.A.U.G, meeting. Portions of this 
letter, along with your supporting 
signatures, will be included in another 
letter to let a few publishers (software 
and magazine) know that a strong market 
continues to exist for Atari 8-bit 
software, especially here in Huntsville, 
Alabama . 

FROM YOUR EDITOR 

Leland Gardiner has come through 
with help for this issue of the 
newsletter. Bob Russell, Jim Collins and 
Bill Powell are also going to help. They 
are giving time to the club by typing in 
articles for the newsletter and helping 
with the BBS uploads. This is a big help 
to me and should help improve both the 
news letter and the HAUG BBS , This is 
the kind of help needed to really get the 
club rolling again. We now need somone 
to take on the task of listing the 
meetings in the local media. Setting up 
"the list should take an hour or two. 
From then on it's just a matter of 
calling or sending post cards every 
month, Six or mere local papers (company 
and regular) plus both cables and many 
radio and TV stations give free meeting 
notices to groups such as owens. 

For other newsletters and new 

members , The HAUG newsletter is 

available about a week before the mailed 
copy by calling either the HAUG BBS (205) 
461-7833 or Bloom County BBS (205) 

7 72-7103. Some past issues are on line, 
Sys-Ops, could Fnet be used to exchange 
newsletters? I don't mean a complete 
newsletter, but normally only the part 
that is not copied from others and would 
be of interest to other clubs. This 
would be a BIG help to many of us 
newsletter editors as it could provide a 
quick way to do exchanges of new 

information and reviews, and provide 
better coverage to our members. It would 
also be a very useful function and 


provide a REAL service for ALL club 
members and not just modem users, 

Elections for club officers will be 
in December, which is only THREE meetings 
away, so be thinking about who you want 
to guide the club in 19SS, How about 
YOU? Unless there is a date change, 
there will NOT be an 5T-SIG meeting in 
either November or December, The 
December meeting will be a combined 
general and ST-5IG for the elections. 

There are only FOUR meetings before 
the IEEE Faire. Again, it is NOT too 
early to develop demos or make plans to 
support the club and Atari at the Fairs, 

From the SLCC Journal - John P , 
Salva, a club member, had the following 
in part of an article: "My partner and I 
decided to turn the results of our 
fiddling into a marketable product, so we 
created Hayward Computer to produce our 
line of disk drives. We are currently 
offering a 360K 5.25" disk drive which 

has its own power supply and will plug 
right into the ST for $199. We also 
offer this unit in kit form for $175 
($150 for unit less power supply; this is 
intended for those who want to use their 
exiting Atari disk drive supply), and for 
those die-hard hackers, the cable alone 
and construction plans for $20, We are 
planning to introduce a line of 3,5" disk 
drives and a combination 3.5"/5,25 rr drive 
for those of you who haven't yet 
purchased a second drive and are trying 
to decide which type of drive to buy."

Atari's own Financial picture has 
improved lately. In the latest quarter 
[2nd], its proFits were $13,54 million, 
while revenue rose to $70,63 million. 
First quarter sales were $65,13 million 
with a net income oF $15,25 million. 
This is $135,6+ million in first half 
sales and $28.0+ million income. At this 
rate, Christmas sales could push them to 
near $.5 billion by the end of 1987 as 
most computer companies are said to make 
70% oF their sales in the second halF oF 
the year, JT is three years into his 
Five year goal oF making Atari a $1 
billion a year company. Now iF he can do 
with Federated Stores what he did with 
Atari, he will really be bringing in the 
cash . 

The ST-TransFormer which emulates 
the 8-bit Atari 800 will be released to 
the Public Domain in ST-Log (From 
Analog) , 

Want so Ft ware for your 8-bit Atari? 
Then write for a Computer Direct catalog. 
It lists Atari and Apple software. There 
is as much Atari as Apple listed in its 
64 pages, with many, many listed For both 
machines, I never saw so much Atari 
software offered by one company,

One Apple owner at work says he has had 
very good service from them. They give a 
15 day free trial period and have a 90 
day replacement policy . 

The ST can now have over 1500 colors 
on the screen at one time, or so the 
claims go, COLORBUST 30001 [$19.95] V 
1.0 from BEERY 1 S BIT SOFTWARE, 8174 
Century Circle East, Suite 8, 
Indianapolis, IN 46260, Has a palette of 
3375 distinct colors. Import Degas and 
Neo pics. Has Calorburst slide show 
program. 

Spectrum 512 is coming from Antic 
with 512 colors [up to 48 colors per scan 
line]. Import Degas, Neo, IFF, HAM Amiga 
[4,096 colors converted to 512 colors), 

GFA-Fi lm From Michtron displays 1088 
colors at one time in low res and 288 at 
one time in medium res. The ST looks 
like it is getting very close to the Hold 
and modify [4096 color] mode of the 
Amiga . 


On the sound end, the ST can go 30 
HZ to beyond audibility in three voices. 
The Amiga has four voices (stereo 2+2} 
limited to well under 10K Hz, or so I 
have read. The best sound depends on 
what YOU need or want. I for one, don't 
care one way or the other, 

STWRITER V2.0 is now available, 
It f s nice. I can't detect any real speed 
difference except in mass character 
delete using the delete key, and then the 
slow down is VERY small. It can be run 
just like the older versions or in a 
semi-GEM mode, and you can switch back 
and Forth between the two. In GEM , you 
can use the mouse to position the cursor 
[real nice] , you can load or merge a File 
using the GEM window to select the File 
(great), and you can use the pull-down 
menus [so-so] . However, when in the edit 
mode you can't access GEM without using 
Esc to exit to the GEM menu screen. You 
can then "mouse off" to the old menu 
screen. In the edit mode, the screen 
looks and can work just like the non-GEM 
version , CAUTION' Take care in what you 
do as it is easy to delete a file when 
you don't want to, I deleted this one 
but had it 95% backed up. Did the same 
thing with the older STWRITER also. Just 
don't change disks or click on things to 
fast as you may be sorry. The delete and 
format options should be under a 
different drop down box. Although I 
think my problem was the loading speed 
given me by DISCACHE. I assumed I had 
not had a successful load and played with 
the boxes, 

COMPUTAH - The Physics S. Astronomy 
Dept. of Michigan State University as 
still using 8-bits in their computer 
labs. The Cyclotron Lab just discovered 
the ST, and are using several to replace 
Techtronics Terminals. They are saving 
big bucks and getting a local CPU too, 
FERMI LAB , the country's largest partical 
accel lorator , is also buying ST's now 
that MSU folks have taken the ST's with 
them on their many trips to FermiLab. 
Thanks to John Nasgy for that

COULD YOU USE A BATTERY BACK UP ? 

By Cave Porter [Edited - ED HAUG] 

New Orleans ATARI Users Group. 

You may want to consider battery 
back up power For the same reason I built 
one for a Friend of mine. His 2 year kid 
recently unplugged his computer with two 


Page 3 


hours worth of composing and key strokes 
in memory, I once told my wife she could 
use the extension cord (that at the time 
had my computer plugged into it) and with 
out a thought let her unplug my computer 
with 13 pages of word processing document 
in memory, unsaved of course. For those 
reasons or if you happen to feel 
unexpected power failure is likely to 
ruin your important work before you save 
it, this may be for you. 

This lets you use four nickel 
cadmium rechargeable batteries , These 
four batteries are rated at 1.2 volts per 
cell and therefore will give 4,8 volts 
when used in series. (End to end) Sure 
these batteries are more expensive but 
for less than the cost of a box of cheap 
no name disks you can do the whole thing 
and only once. Flashlight batteries will 
only work their life cycle and then need 
to be replaced. About $10 even at the 
most expensive retail prices should do 
this project. A lot less if you shop 
ri ght , 

Before you blindly do this, or 
before any of you more technical users 
question if I did my homework , let me say 
this only to give you some confidence in 
the idea . X am a degreed engineer and 
have attended schools on nickel cadmium 
batteries for both application and 
maintenance theory. And over the last 15 
years I have developed several ni -cad 
Cnickel cadmium) circuits for use in 
medical, marine, and field monitoring 
instruments for the oil production 
industry. In fact one typical benefit 
For using a ni-cad parallel system is it 
is one of the more reliable low voltage 
stabilizers available. That is, this 
circuit will provide excellent protection 
from small increases or decreases in 
supply voltage thus protecting your 
computer not just the data. 

Use two crimp splice connecters. 
These are used in several automotive 
applications, everything from trailer 
light connections to the new cyclops stop 
light connections. All you need is two 
such connectors from RADIO SHACK or 
automotive parts house, a Four ceil 
battery holder, four nicsd batteries, and 
a small length of flexible zip cord 
wire , 

Take a small hobby type knife or 
thin knife blade and split the insulation 
along the grove of your ATARI power 
supply about six inches from the din 


connector that actually plugs into the 
back of the computer. If you do this you 
will not have damaged the insulation in 
any way but rather separated each of the 
two main wires supplying the 5,0 volts dc 

to your computer. No wire skinning is 

necessary on the power supply if you use 
these crimp type wire splices. One side 
of the power supply card is clearly 

marked with a white stripe. This stripe 
1 s the plus 5,0 volt connection and 

should with the crimp splice be connected 
to a short length of wire to the plus end 
of your batteries. If you do this 
correctly success is guaranteed. Just 
make the other connection ta the opposite 
wire end apposite end of your batteries 
and you should be finished. 

You may get by on the smaller double 
a size batteries but they will only power 
the typical XL/XE for about 23 minutes. 
More than enough time to save your data 
during short duration failures. 
(Remember your disk drive won't work 
either). If your failure is limited to 
some careless unplugging at the wall, 
this would be plenty of time to reclaim 
your system without loss of data * On the 
other hand, you could use some surplus 
batteries found in your unused grass 
clippers out in the garage, these sub C 
size batteries will provide complete 
computing power for up to one full hour 
or more. Additionally these batteries 
will not over charge and can be left 
connected permanently. Like your 

electric toothbrush, connected like this 
the batteries will receive a very small 
charging current bath during and after 
computing and should be Fully charged, 
ready and available at all times. Figure 
the charging current to be approx, 65 
miliiamps with your computer off and 
about 50 miliiamps with it on. This 
amount of charging current should not put 
any noticeable strain on your power 
supply and falls right in accepted limits 
for what is called a n C 10 Tt charging 
rate. That is ten percent of the rated 
batteries capacity. The slight variance 
in charging current is due to the small 
drop in output voltage when the computer 
is operational, I have used this setup 
for several weeks now and have enjoyed 
the confidence I have knowing my wife 
won't place my system in failure mode 
using the vacuum cleaner, and your two 
year old can pull on my wall cord without 
me having a heart attack*

OQM IS SACK! 

By Jim Gross 

Well j after a long dry spell, the 
Disk-of-the-Month is beck! The Advanced 
Music System [AMS] by Lee Actor is 
perhaps the most popular music composer 
system ever written for the Atari * There 
are literally hundreds (maybe even 
thousands] of AMS songs available. Most 
club disk libraries and bulletin boards 
are full of them . except ours! So for 
this month, I had planned to pull 
together some of the best of the AMS 
music files and a public domain player. 
Several players are available. All of 
them do the job, but some run from Basic 
and some will not run on the XL/XE 
machines without the translator disk. 
The one I planned to put on this month's 
disk is a relatively short machine 
language File which runs on any S-bit 
Atari without the need for a translator. 
As a bonus, it displays a "player piano" 
keyboard which indicates each note 
played. Each of the four Atari sound 

channels is displayed as a unique color 
on the keyboard as the music plays. 

Well, as I said, I MEANT to produce 
a disk full of the best of the AMS files. 
However, as I searched through the 
available Atari music, I found a couple 
of other programs that I thought you 
might be interested in. One is a totally 
awesome demonstration of Pokey Power 
called the Rotburg synthesizer. It uses 
machine language control of the output 
waveform to simulate the sound of actual 
musical instruments and percussion. The 
Rotburg rendition of Ravel T s Bolero will 
blow your mind! 

Another neat music system which I 
just discovered is called the Advanced 
Music Processor (AMP]* Not to be 
confused with AMS, the AMP system was 
written by Philip Price and has 
apparently been used to produce 
background music for commercial games. 
Only about 20 or so songs are known to be 
available for this system, and some are 
not in the public domain due to existing 
contract restrictions . AMP version 11.4 
utilizes redefined character sets and 
fonts to display full screen lyrics and 
animat ion while the music plays. A very 
interesting demonstration of the power of 
this system was written for ANTIC 
magazine . 

As you can see, my original idea of 


an AMS disk got a little out of hand. 
What to do? The Rotburg Synthesizer is 
by far the best of the lot when it comes 
to realistic sound, but the four or five 
songs contained in the program really put 
it more in the demo category, AMS is 
really old stuff, although we don't have 
a lot of material in our library (I hope 
to change all that]. As for AMP, I'm not 
sure I can find enough AMP songs to fill 
a disk. 

So, just exactly what is the October 
Disk-of-the-Month going to be? I haven't 
decided yet! Tune in next meeting and 
see! Whatever it turns out to be, if you 
like Atari music, you won't be 
disappointed. 

ATARI BULLETINS 

(9/17/07) The XEPS0 80 -column 
adapters are in the Atari warehouse in 
Sunnyvale and are available for immediate 
shipment to dealers. The XEP80 plugs 
into the 2nd joystick port of any Atari 
Q-bit computer , Any video monitor can 
plug into the XEP80 and deliver true 
80 -column text. An extra part on the 
XEPB0 allows standard parallel printers 
(ST or IBM compatible) to plug directly 
into the B-bit Atari computers. The 
driver program for the XEP80 lets it take 
the place of the E: device. Software 
that is compatible with the E: device 
(such as Atari BASIC] will work in 80 
columns without modification. Other 
software that writes directly to the 
screen (bypassing the OS] would need 
modification before working in 80 
columns. Atari is working on Atari Writer 
80 and Silent Butler 80 to support the 
XEPS0 . Delivery dates on these products 
are not yet set. The XEP80 retails for 
$79.95. The new XE Game System has also 
arrived in Sunnyvale and is on its way to 
toy stores and other retailers in the 
USA. The XE Game System retails for 
$149,95. It comes with a sophisticated 
keyboard, a light gun, and three top 
games including Flight Simulator II, 
Missile Command, and Bug Hunt. 

(9/11/87) The Atari SX212 modem is 
currently shipping to Atari dealers in 
the USA. The first shipment arrived at 
the Sunnyvale warehouse during this past 
week. The SX212 is a Hayes -compatible 
modem which operates at 1200 baud (and 
also at 0-300 baud] . Its 

Hayes-compatibility extends to the 
S-registers , The SX212 modem includes 


Page 5 


bath the standard RS232 part and the 
Atari 0-bit SIO part . However , S-bit 
users should be aware that the software 
to support this modem through the SIO is 
not yet released — in the meantime, the 
modem can still be used through an 850 or 
equivalent interface. The modem package 
includes a power supply (identical to the 
£600*5), a detailed manual, and special 
offers from the GEnie (General Electric] 
and SIX (Byte Magazine] online services. 
To connect the SX£1E to an ST or to any 
other R3£3£-equipped computer, a full 
RS232 cable is needed -- a 3-wire cable 
does not work with smart modems. When 
the software is ready, Atari will market 
an add-on package For 8-bit users. This 
will contain an SID cable and a disk 
which includes the modem driver and the 
5X Express terminal program by Keith 
Ledbetter, The suggested list price of 
the 5X£1 £ modem is $99.95, -

HOW TO LISE ARC for 8-bit Atari 
ANTIC PUBLISHING, COPYRIGHT 1987 
An ARC (pronounced "Ark") file 
contains one or more files which have 
been compressed into a single file. Use 
ARCX.COM to extract the files from the 
.ARC file, ARCX is a machine-language 
program which requires at least 48K. 

ARCX.COM may be downloaded from the 
Utilities section of the Atari 8-bit SIG 
.(type GO AT APIS). 

HOW TO USE ARCX. COM 
Before running ARCX be sure you have 
removed all cartridges and BASIC is off. 
Now load ARCX, COM from DOS (use DOS menu 
choice "L"), or type ARCX if you are 
using Sparta or an OSS DOS. 

ARCX will ask you for the name of 
the ARC file to extract files from. (If 
you dan T t remember the filename, you can 
get a directory by pressing the [ + ] 
key. ) 

After typing-in the name of the ARC 
fiie, ARCX wiii ask you for the drive to 
send the extracted files to , ARCX wiii 
extract ail files from the ARC fiie and 
write them to the destination drive. 

Next, ARCX will ask you if you want 
the screen turned off. If you press f Y r , 
then the screen will be turned off during 
the extraction process. This will speed 
up the process about 10%-£0%. 

ABOUT ARC 

The expansion algorithms used to 


extract ARC files are quite complex, and 
therefore rather slow, (About one minute 
for each 5K of source file,] 

ARCX uses all available memory and 
buffers the input and output so your disk 
drives won f t be running all the time. 

Keep in mind that the extracted 
files can be more then twice the size of 
the original ARC file. Be sure you have 
enough room before you start l 

ARC was originally written in C by 
Tom Henderson of System Enhancement 
Associates , The source code was placed 
in the public domain allowing for ARC and 
ARCX to be ported to a wide variety of 
computers . For complete instructions , 
refer to the documentation files in the 
Utilities library of the Atari 8-0it 
SIG. 

ZMAGAZINE 69 September 4, 1987 
ATARI T S TRAM I EL REAOY FOR BATTLE 
Quoting Gen, George Patton and 
sounding a lot like a coach psyching up 
far the big game. Jack Tramiei says his 
Atari Carp, is ready to become America T s 
consumer electronics supplier. 

Speaking with business writer Bob 
Webster of United Press International, 
the 59-year-old Tramiei says, ,f 0ne of the 
people I admire is Gen. George Patton, 

In business, whatever we do we go out 
there to win, not to play the sport. We 
have the best product , the best personnel 
and the best locations to make sure we 
win . " 

Atari has made headlines last week 
with its plans to buy out the 67-store 
Federated Group retail electronics 
store . 

Tramiei tells Webster that the chain 
will be a key to his dream of turning 
Atari into a "vertically integrated" 
consumer electronics company. 

"There are no companies of that 
nature left in the United States , M 
Tramiei said. "General Electric was the 
last one. We are going to be an 
international consumer electronics 

company Computers are one of the 

products. Hitachi and Panasonic da not 
only make computers. I want to share my 
(research and development) costs, from 
designing and planning a product from the 
component to the shelf. This is the way 
my competitors in Japan have done it for 
m number of years." 

Of course, Tramiei is not talking a 
great deal about future products, but he 


Page 6 


did tell UP I he now plans to oversee 
Atari 7 s development of a CD-ROM product 
to be introduced this fail- He also said 
Atari is negotiating with several 
semiconductor companies for a passible 
acquisition . 

Of the Federated acquisition, 
Tramiei says the company hopes the chain 
will strengthen its sagging distribution. 
"Instead of waiting for three or four 
months to get a reaction from retailers, 
by having an outlet I can tell in six 
days , " Tramiei said • 

Webster comments that "most previous 
ventures by computer companies into 
distribution have failed, except for 
Tandy Carp . r s efforts through its Radio 
Shack outlets. But distribution alone 
does not appear to underscore Tramiei *s 
pursuit of Federated." 

That 7 s the view of^ Jan Lewis , 
president of Lewis Research Group of 
Sunnyvale, Calif., who told the wire 
service, "On the most simplistic level, 
[Tramiei] wants to buy distribution. But 
I think his plans may be broader than 
that. Tramiei comes from retailing and I 
think he may see farther than others in 
the marriage of computers and consumer 
electronic products." — Charles Bowen 

□BASIC - #3 Upgrade 
By Levin Soule 1 

The last disk update, number three, 
to D BASIC was received on 4 September. I 
will not be at the next 5T-SIG, 
Therefore, mail me a disk folded in a 
SASE and I will mail it back. It comes 
to me In a common envelope, inside two 
sheets of folded paper, without any 
problems. It now does what the manual 
says. They are now going to look at 
sound chip and RS-232 support. Future 
upgrades will be from their BBS, (505) 
963-9578 , They will also publish an 
electronic newsletter (NEWSLET1) about 
Oct 1 , and post demos , updates , patches 
to the 27 Aug (latest) 08A5IG, and 
utility programs* (No uploads to their 
board, ) 

TURBO BASIC COMPILER PROBLEM 

By Jeff Cole hour S. Dick Hearse y 

Edited for M.A.C.E. by Doug Miller. 
The new TURBO BASIC system has been 
discussed in many publications and is 
truly an outstanding basic for the 8-bit 
ATARI. It is not only much faster than 
ATARI basic, but it also has a compiler 


that provides an additional increase in 
speed for most applicat ions . A few 
limitations on the types of basic 
commands that can be used with the 
compiler have been presented, but we have 
found another limitation that might be of 
interest to any one who is considering 
using the TURBO BASIC COMPILER. The 
problem has to do with arithmetic 
operations on singly or double 
subscripted variables. The short program 
shown below works correctly when using 
the TURBO BASIC INTERPRETER only, but 
gives an error when run in the compiled 
mode. This is followed by a simple work 
around that does work in the compiled 
made . 

10 REM TURBO BASIC COMPILER 
20 REM SUBSCRIPT PROBLEM DEMO 
30 DIM MAT( 3 ] 

40 MAT ( 1 ] =1 
50 MAT ( 8 ] =2 

60 MAT(3)=MAT(1 )#MAT(2) 

70 ? MAT( 3 ] 

80 END 

The result of running this in the 
compiled made is error 9 in line 
0060: array or string dim error. A Fix 
for this Is to change line 60 and add 
line 65 as shown below: 

60 Z-MAT[ 1 )=t'MAT(2 ] 

65 MAT( 3 ] =Z 

The limitation is apparently that if 
arithmetic operations on subscripted 
variables were performed on one side of 
the operator a subscripted variable 

cannot appear on the other side. The 
arithmetic operation is part of the 
problem because a statement such as 
MAT ( 2 ) -MAT ( 1 ) does not cause an error. 

We have also encountered similar 
situations in which no error message was 
given, but incorrect results were 
obtained when running in the compiled 
mode. If subscripted variables are being 
used it would be advisable to carefully 
compare results obtained from the 
compiled and interpreted modes. This is 
not a serious limitation, since the work 
around is fairly easy, but it could 
require code modifications to permit use 
of the TURBO BASIC COMPILER.
