the kept debugger must be run as a multi-process debugger

    Facility: DEBUG, VMS Debugger

    Explanation: The kept debugger must be a master process running
    and rerunning programs as subprocesses. This is not possible for
    a one process debugger. The kept debugger must be run using more
    than one process.

    User Action: Correct the logical name assignment for DBG$PROCESS
    to be either "MULTIPROCESS" or "DEFAULT", and try again.
