: : Most of the programs which run with BASICA will run properly with Microsoft QuickBASIC. You should download the version 4.5.

: : Thanks Davi, but I looked into QBASIC and there is way too much code to convert, plus there is also a question of compatability - especially in how QBASIC differs in its recognition of input EOF. Because I execute BASICA from within hundreds of (mostly very) large BAT procedures, the easiest solution would be to provide a patch fixed version of BASICA to all systems running this code. The patch, or at least knowledge of what needs to be fixed, is really what I need. Bill.

:FOLLOW-UP: I parallel DEBUGged the same BASICA using the same IBM-PCDOS 6.2 on two different systems:
My PS2MOD35 where BASICA runs successfully
My slowest PENTIUM III system where BASICA hangs with a blank screen and no cursor (and absolutely no keyboard response, including CTRL-BREAK and CTRL-ALT-DEL, i.e. a total complete hangup where the computer has to be turned off and restarted to purge the hang).
Everything is fine until shortly after the first INT 10H which I assume must be an interrupt into BIOS. At this point, the traced code varies so drastically that I couldn't determine any parallelism at all except that finally an INT 67 is issued at which time the PENTIUM III system hangs.
At this point, it would appear that BASICA utilizes some feature in BIOS which is not supported on the newer systems. Guess I'll try another query to IBM and see if I can get some sort of response - I can't believe that they wouldn't support one of their own software items when so many of their customers must have come to rely on it - or did all BASICA users convert to QBASIC? Considering the amount of recoding and retesting I'd have to do in order to convert, I kinda doubt it.
If this follow-up tweaks someone else's memory as to what to fix, please respond here. Thanks, Bill
