I have several versions from both the CP/M Archive and Retroarchive. The
version numbers are all messed up, but I think I've tried 5.21, 5.24 and
5.29. A friend of mine is double-checking by CBIOS on his machine to
eliminate the CBIOS as an issue. It's very odd. Every other program I've
tried (including TinyBASIC) works...just not MBASIC.

If you have a known-working version and can send it along, I'd appreciate
