Well CCP is a user interface as is command.com, changing out command.com
for Win3.1 still doesnt change the fact that it's a DOS OS with a GUI
instend
of Command line.

So goes it for CP/M, CCP or ZCPR are only a 2k loadable module that can
be replaced with anything. For example CONIX is one that can be run over
CCP for a unix like command line.

It's part of the line starting with P2DOS, suprbdos, Novados, Zdos
and a few I may have forgotton. Their rewritten versions (some from
virgins) of code that is CP/M files and program compatable. Most
Z80 code, faster and most also offer a higher (1gb) logical drive
size limit.

Not really. I have CPM3 and MPM as well. The bios is a bit more
convoluted
to allow for memory management and interprocess communication but
most of the differences are transparent. the Docs for those two are
noticably
weaker and add an air of mystery.

I've taken the path of adding job scheduling and interprocess managment
to cpm2.2 as it had nothing to prevent it.
