[comp.os.cpm] Public File Access in CP/M 2.2

SAGE@LL.ARPA (04/13/88)

   Brian Lair asked about gaining public access to files in user 0.  The
Echelon Z System (with ZRDOS) allows files in designated directories to
become public.  There is also a patch from Plu*Perfect (perhaps Bridger
Mitchell will leave a message on where it can be found) that implements
something quite similar to the CP/M-Plus system.
