Hi.  I'm interested in finding out whether the addresses 57H through 59H in
the base page ("System Parameter Area") are used in any variant of CP/M.  I'm
especially interested in whether CP/M Plus uses these addresses.  (They're
listed as "reserved" in the CP/M 2.2 and MP/M II manuals).

If anyone's interested in what I want to do with these addresses, think about
argv[0] (that's the way the command name is passed to the program, for those
of you who don't recognize that from C and UNIX)...  I'd like to propose that
those addresses be reserved for that purpose (along the lines of the way MP/M
II stores info about the passwords from a command line), but I need to find out
if there are any conflicts first...

				Thanks in advance!
