     Modified source from SPRING '82 tape (directory [312,331])

     The PAC game was given the following modifications.

     1) When two or more PAC games were in the system, the throughput
        of the game was horribly degraded.  I noticed that the
        game was written to do a QIO for cursor control and a QIO to do
        single character outputs.  I combined the cursor control and
        single character output into one QIO called CPP (cursor control
        and print).  The game was much faster and with multiple PAC's in
        the system, the individual games did not degrade as much.

     2) I overlaid the program in such a way that no degradation of the
        program was allowed during execution.  This was to allow many PAC's
        to run on small memory systems.

  ** 3) I added the saving of high scores and initials.  This was desired
        to allow competition with other players.

     I know it works fine on RSX11M system (11/44 or 11/60).

     To compile the program, use PACASM.CMD

     To taskbuild the program, use PACBLD.CMD.
     NOTE you will have to change the resident library definition (LIBR=...).


     Have fun!!!!!
