PATCH 

You may only use PATCH on compatibility mode (CM) programs.  Use it to
access, display, and/or modify a program file's object code without
recompiling the program.  You can make simple changes to program
instructions or to global stack area variables.  PATCH requires the
memory location of the target program symbols, the beginning locations of
each program unit, and the offsets for each line of code from these
locations.

              or     
     PATCH               RUN PATCH.PUB.SYS 


CAUTION  PATCH bypasses normal MPE/iX safeguards and will modify the
         contents of privileged program files.  When attempting to modify
         privileged data on disk, it is possible to destroy file
         integrity, or the MPE operating system itself.  Hewlett-Packard
         is not responsible for changes you make to the operating system
         or system files.  For more information, talk to your
         Hewlett-Packard service representative.
