This may have zero relevance, or... When attempting to run CPACK under a DOS Emulator (albeit on a Nokia Communicator) had to delete the line cg.com from the app200.bat file for it to work. FWIW.

A good suggestion, SNi, but no joy. Turns out that the cg.com TSR handles the special CGA screen calls in place of the real 200LX hardware. The reason that some systems, like the Nokia, need it removed is that they already have the 200LX calls in native OS. Not so Bochs or the Z.
By putting \"pause\"s everywhere in APP200.BAT, I was able to narrow the problem a bit. UN200 executes OK. SO do cg.com & tkernel. When LAUNCHER.COM tries to run, it freezes the DOS session.
Without cg or tkernel, launcher abends with a very fast \"TSR not loaded\" warning and a clear screen.
In theory, from what I\'ve read today, ANY System manager compliant DOS app could be run in place of launcher in the BAT file. Or even just by loading cg & tkernel first.
So I\'ll keep researching Bochs & CPACK to see if any answers popup. Let us know if you think of anything else to try!
THANKS!
