[net.micro.cpm] Are locations 57H through 59H used?

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!
