I have worked many GPIB programs in QuickBasic. I recently sent a e-mail
to national Instruments concerning writing programs with DJGPP and also
GNAT ADA.
Below is the answer I received, though I didn't find it of much help, it
might help you a little bit
Good luck... Vince
Subject:
gpib programs
National Instruments
I am inquiring if the GPIB-AT & PC-GPIB programs can be made with a
C/C++ compiler program called DJGPP, or GNAT Ada, an ADA compiler which
is a 32 bit DOS based program. We have been using QuickBasic but would
like to change over to either one.
Thank you.

Dear Vincent,
We do have a DOS Extender Language Interface, but it is written for
C/C++.
I seriously doubt that you would be able to link in one of the existing
.OBJ files with your ADA app. You could try though. If you are
interested,
you could buy the source code and convert the C calls to something that
ADA
could handle. The hardest part will be going from protected mode to real
mode. In some cases (like the Borland C DOS Extender LI that works with
Borland Power Pack) we had to use Assembly language, in other cases, we
were able to use one of the DOS Extender's calls (like Phar Lap with the
Borland C DOS Extender LI) to do the "dirty" work for us.
Nobody here is very familiar with ADA and I do not know if you can call
assembly routines or use inline assembly routines. Therefore, I am not
sure
if ADA is up to the task or not.
Best regards,
Eric Singer
