[net.micro.apple] How standard is Apple CP/M? DR update to version 2.23.

I've been familiarizing mysef with the CP/M world via a Softcard
and Apple II+ combination.  As you know, there exist other Z-80
cards which will also work within CP/M.  My question concerns
what people call standard CP/M. Given any program written for
the CP/M operating system, what if any changes  are required to 
adapt it  to Apple CP/M ? Is there such thing as a standard set of changes
to be made? What books detail this information?

I can see that if the Apple CP/M is a superset of the standard CP/M
system; then no problems shoud arise unless the program written
specifically for Apple's version is run on a standard system.

DR's version 2.23
------------------

I d'ont know if the new version of CP/M from "mom" is a mixed blessing.
It provides 4k more room for the TPA, but has changes things in the
BIOS and DOS .  A  friend of mine's says that older files are
generally readable under the new system. But ultilities which
modify system dependent parameters will also have to be changed.
For exampble, He can no longer use his existing 'init' file
to set up his "Saturn 128K card" as ram disk under version 2.23.
Is anyone out there familiar with the advantages, diaadvantages, mods
required to existing stuff , etc resulting from the new release.

P.S. Does BDS C run on Apples?
