GFACUST.GFA - CUSTOMIZING PROGRAM FOR GFA BASIC 3.0
Version 1.0 (09/88)
By Don Bush (GEnie ID: D.BUSH)
WARNING:
NEVER CUSTOMIZE YOUR ORIGINAL COPIES OF GFABASIC.PRG or GFABASRO.PRG!!!
ALWAYS make a backup copy and customize the BACKUP ONLY!!!
This program will let you easily customize the GFA BASIC 3.0 interpreter
and run only programs. You should have no problems using the program, as
it uses the GEM interface and is quite self-explanitory.
The following files are included in the GFACUST.ARC file
*GFACUST.GFA - The program
*GFACUST.RSC - The resource file for GFACUST.GFA
README.DOC - The file you are reading now.
GFACUST.RSD - K-Resource definition file
GFACUST.DFN - Atari RCS definition file
* = necessary to run GFACUST.GFA
NOTES:
The file GFACUST.RSC must be in the same directory with GFACUST.GFA
This program runs in medium and high resolution only. This is
because some of the dialog boxes will not fit on the screen in
low resolution.
This program uses the locations documented in the README.303 file
included on the GFA BASIC 3.0 disk. If these locations are changed
in future releases of GFA BASIC then this program will not work.
PROGRAMMING NOTES:
The source code is included in the ARC file for those of you who
may want to study or modify it. It is heavily commented and offers
examples of many of the GEM library functions.
I developed the resource file using K-Resource from Kuma Computers Ltd.
The resource construction program uses a special file to keep track
of the names of the trees and objects.
K-Resource uses a file with the extender .RSD. The RCS program included
in the GFABASIC 3.0 package uses a file with the extender .DFN.
I have included both GFACUST.RSD and GFACUST.DFN so you may use the
resource file with either RCS program.
(You can make a .DFN file from a .RSD file as follows: First make a
copy of the .RSD file and change the extender on the copy to .DEF.
Now you can run the DEF2DFN.PRG program supplied with GFA BASIC
to convert the .DEF file to a .DFN file.)
I used Mark Petersen's K_RSC_TO.GFA program to convert the .H file
from K-Resource to a GFA BASIC .LST file. This program is available
in the Michtron RT on GEnie. The file name is K.ARC and the file
number is 1185. If you are using the ATARI RCS program that comes
with GFA BASIC then you will not need this program because the
ATARI RCS produces the .LST file directly.
