Having made the switch from a model 1 TRS-80 to CP/M a number of years ago,
there were a few things about the TRS-80 that I missed.  One of these was
the SYSTEM command, that allowed me to jump anywhere in memory.  Thus arose
SYSTEM.COM for CP/M.  Just simply a dumb program that emulates the TRS-80
SYSTEM command.  Typing SYSTEM at the A> prompt, gets you the familiar
*? prompt of the SYSTEM command.  You may, just as on the TRS-80, type a
slash (/) followed by a decimal address, & control will be transferred to
this address.  An improvement over the TRS-80 command is the acceptance
of hex addresses if typed in directly, without the slash.  (After all, we
aren't going to load anything from tape!)  Either way, the processor jumps
to the specified address.  Useful for jumping to ROM monitors, etc.

but no guarantees are made, & the user assumes all responsibility for any
