[micro.ibm] Looking for a Wizard in IBM Compiled Basic

usgrif@ecsvax.UUCP (Steve Griffin) (07/13/89)

I have been asked to fix an old program written in IBM compiled
Basic version 1.0 (circa 1982) and I need some information that
is not covered in the original manuals.  If you have experience
linking external assembler routines with compiled IBM basic, I
would greatly appreciate receving email from you.
 
The program in question does direct screen memory manipulation
and therefore causes snow on CGA screens.  I have two asm
routines that move data to and from the screen, respectively.
The routines work fine as long as there are no CHAIN statements
in the progra  Errors range from system lockup to "String
Space Corrupted".
