Subject: ZCPR2 Utilities under CP/M

Yesterday Keith asked if the ZCPR2 utilities can be run under normal
CP/M 2.2, and we thought the response may be of general interest.
By and large, the answer is YES.  The GENINS program must be run on
all of the utilities to do this.

GENINS is used to install utilities in a ZCPR2 environment, and such
utilities can be installed with all ZCPR2-specific features turned
off.  As a result, the utility does not try to reach into ZCPR2 for
buffers and the like, and ZCPR2 and CP/M are identical to it.  The
installer need only turn off all of the ZCPR2-specific features:
no external path, no multiple command line (address 0), no memory-based
named directories, no disk-based named directories, etc.

Most utilities will continue to function with these turned off.
Some, however, like MENU, will not, since their function is based on
using ZCPR2.  These utilities will tell you they can not run if you
try to run them after turning off the features.

One nice feature in all of this is that by turning off external paths,
the internal paths, if you so desire, become operational.  In other
words, utilities may use their internal paths under CP/M 2.2 to perform
their functions.  Hence, file searches performed by the utilities still
work, and some ZCPR2 functions, in a limited sense, are moved into the
CP/M 2.2 arena.
