| 1148.1 | System calls via GFA BASIC | AIDEV::HUTCHINSON | Hutch | Mon Jun 24 1991 11:40 | 20 |
| Theo--
I assume you have the manual for GFA BASIC 2.0. In an appendix in the back is
a fairly good listing of most of the XBIOS, BIOS, GEMDOS calls. GFA makes these
calls essentially the same way most C compilers do; nothing special to it.
Some of the most popular ST reference books are the Abacus series, including
"ST Internals" and "GEM Programmers Reference Guide". If you can find them,
Compute published a couple of reference guides to the VDI which were quite good.
GFA Data Media publishes some books of general interest for GFA BASIC users:
"Software Development using GFA BASIC 3.0" and a couple of others. One was
written specifically for 2.0 as I recall.
If you don't have the 2.0 manual or even if you do, I strongly suggest you
upgrade to 3.0. The manual is worlds better and considerably thicker due to the
300 some odd NEW commands. It's much faster, desk-accessory compatible, and
even the editor is improved. 2.0 was good but falls far short of 3.0. Do it!

| 1148.2 | there is a help file somewhere! | UKCSSE::KEANE | | Tue Jun 25 1991 04:44 | 14 |

GFA basic V2.0 was given away a couple of times on "free" magazine
disks.
One of the disks also had an online help file which gave a short
explanation of most of the calls. I cant remember whether it included
the ones you are after.
Does anyone else still have the disk, I think it was an ST Format mag
giveaway?

| 1148.3 | thanks | JGODCL::MULLER | | Mon Jul 01 1991 04:23 | 10 |
| Thanks all for your replies,
I think I go to find some of these books or disks.
But if I go to upgrade to vers. 3.0, can I still run vers. 2.0
proggrams??
Thanks all,
Theo

| 1148.4 | GFA 3.0 is downward compatible | AIDEV::HUTCHINSON | Hutch | Mon Jul 01 1991 10:41 | 11 |
| Theo,
GFA BASIC 3.0 is totally downward compatible with programs written in 2.0.
Just save your 2.0 GFA programs in ASCII format with the "LIST" command and
then use the "MERGE" command under the 3.0 editor. You can doublecheck your
program's syntax with the F10 key. On very rare occasions, you may find an
offending keyword that 3.0 doesn't like and these will be marked with a "==>"
symbol. Correct these and you are off and running.
