 cross-process signal system service is not available

    Facility: DEBUG, VMS Debugger

    Explanation: The debugger was unable to execute the specified
    command because the cross-process signal system service is not
    available in this version of VMS.

    User Action: Upgrade to a version of VMS that has the cross-
    process signal system service.
