Executing a ProDOS bye:
1) Call the MLI "bye" command.           (sorry  :-) )
[ 300:20 0 bf 4 65 0 0 0 0 n300g    ...I think... ]

Executing another system file:
1) Read the file into memory at $2000
2) jmp $2000

The read routine isn't hard to code... just do a GET_EOF on the file
and then do a READ for that number of bytes.  Add a few OPENs and CLOSEs,
and you're all set.
