EDITORIAL
=========
MEMBERSHIP
----------
As a result of the article in Atari World magazine we have had 19
enquiries about the group this month of which 17 have joined so far,
welcome to all of them. Unfortunately a few members have also dropped
out this month, Jonathan White has moved to the Apple Mac and Ralph
Lovesy is now writing games for the PC. However, we still have over 50
current members which should be enough to keep the magazine going for
a long time yet.
We would like to see more feedback from members on what you want to
see in the magazine and we would like to have more letters in the
correspondence section below which is a bit sparse this month. If you
have a programming problem, or a solution to somebody else's, please
send it in. If you send in a replacement disk for next months issue,
put a short letter on it with a programming query, comments about the
group, some aspect of programming or whatever. Although we have a
number of PD articles/programs available for the disks, we would
prefer to use original material from members where possible.
DISK FORMAT
-----------
When you send in a disk please use a DS/DD type disk rather than High
Density because we cannot read some disks of this type.
GDOS
----
In the Misc section we have some more information on GDOS and the
AMCGDOS program which was mentioned last month. There was no text file
with this program so presumably it is used in the same way as GDOS but
as it is PD it can be supplied with any PD program that requires GDOS.
We haven't tried it so we don't know how reliable it is, if anyone has
any further information about the program, please let us know.
Also a member has volunteered to write an article on using SpeedoGDOS
from a programmers point of view which we hope to publish in a later
issue. If anyone has any tips on using SpeedoGDOS, please send them in
so that we can include them in the article.

Would it be possible for me to use your GFA librarian program in a
HISOFT BASIC2 toolkit that I am writing. The program and documentation
would remain unchanged, and you would get full credit as the author,
the toolkit will initially only be released to ICTARI, but will be
public domain and will eventually find its way around the houses. An
answer, either personally (my address is in the members list) or
through ICTARI would be appreciated.
To: *.*
If anyone has any useful sub programs or functions for HISOFT BASIC2,
how about sending them for inclusion, the toolkit will be a collection
of subs & functions aimed at TOS programmers, i.e. games or demos, GEM
is not catered for at all, at the moment all I really have is hidden
screen and blitter routines. Anything you think may be useful would be
appreciated.
*/ As we have about ten or so HiSoft BASIC users and even more GFA
Basic users we are sure that there will be some interest in a BASIC2
toolkit. If anyone has any useful code, please send it in. ICTARI /*

Hum ! Simple question for you lot. I managed to get myself a printer
recently - a Panasonic KX-P1170 9 pin. I have the little problem that
it won't print the # instead it prints , this is annoying when I
print up listings. I know there is a way round this as I solved it
years and years ago when I had a Star LC 10, but I'll be damned if I
can remember it !!!!
This next point is a little more complex.
On some dialog boxes I have come across there has been an underscore
to highlight a keyboard shortcut, alas I am unable to discover how to
achieve this underline - is it an undocumented feature ?
Any help on this would be most welcome.
*/ If you are using DevPac to print Assembler listings, you can use
the LISTCHAR pseudo-op at the beginning of your source code to send a
command string to the printer at the start of printing. The codes
following the command are sent to the printer and can be used to
change the character set, character pitch, or whatever. I normally use
the codes -
LISTCHAR 15,27,82,0
which sets the text to 17 cpi and the character set to USA which uses
the # sign instead of the sign on my Panasonic printer.
Unfortunately this technique only works when the code is assembled and
not if you want to just dump a block of source code to the printer.
However, if you assemble the code first the printer should retain any
set-ups so that subsequent printouts will be OK.
As for the dialog box underlined characters (and how the keypress is
handled), we would also be very interested to see how this can be
done, if anyone knows, please send the information into us. ICTARI /*
