the command qualifier qualifier_name is not available

    Facility: DEBUG, VMS Debugger

    Explanation: The specified command qualifier, although available
    in some debug implementations, is not available in this one.
    One reason why is that the qualifier just doesn't make sense
    on the platform. For example, the /JSB qualifier on a STEP
    command doesn't make sense on Alpha VMS because there is no "JSB"
    instruction like there is on VAX VMS.

    User Action: Reissue the command without the qualifier.
