DEBUG 

DEBUG is used primarily by system programmers, who use it to set
breakpoints within programs, and to display and modify data stacks and
registers.  Access through the DEBUG command is available only to users
with privileged mode (PM) capability.  Nonprivileged users can get
limited access with the ;DEBUG option of the RUN command to debug their
applications; the DEBUG utility will not allow them privileged access to
the system.

              or      
     DEBUG                RUN PROGNAME;DEBUG 


CAUTION  Normal MPE safeguards are bypassed in privileged mode.  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.
