Subject: modem7 jump table

I was aware of the jump table located within the overlay itself and up
until tonight (this morning) I was under the impression that all those
little "DS 3" pseudo ops had to be replaced by "JMP's" into the main
program.

When they call them overlays they mean it.  Those DS's leave nice neat
little undisturbed jump instructions from the orignial .COM file,
"because" as "everyone" know's a DS does not alter memory.

Therefore my overlay, your overlay and everyone else's overlay will
"plug in and play" on any version of MDM7 after it has initially been
customized and optioned.  It's a one shot operation.

P.S. Thanks for the USR overlay Bob,  I'll blend  it with mine and
     shoot you a copy somehow.
