     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 /*
