Subject: ZCPR3 and CP/M 3.0

Yes, ZCPR3, SYSLIB3, Z3LIB, and VLIB all run under CP/M 2.2.  Due to
their direct BIOS calls, they will not run under CP/M 3.0.  Some
degree of modification to the low-level device drivers is required in
order to get the libraries to be useful under CP/M 3.0.

ZCPR3, however, is another problem, since, as a command processor, it
directly loads the COM files it selects, a knowledge of your
bank-switched environment is required.  I suspect that the degree of
modification to get ZCPR3 to run under CP/M 3.0 would be extensive.

Re the files on SIMTEL20 that you referenced, I am not familiar with
them.  I am not moving toward the CP/M 3.0 world.
