/RAD=n
       /NORAD

    Specifies the RAD number on which to run batch jobs assigned
    to the queue. The RAD value is validated as a positive integer
    between 0 and the value returned by the $GETSYI item code, SYI$_
    RAD_MAX_RADS.

    To eliminate the RAD value for a batch queue, use the /NORAD
    qualifier.

    Note that when you change the RAD value on a batch queue, the
    jobs currently in the batch queue are not dynamically updated
    with the new RAD value. Any executing jobs will complete
    processing using the original RAD value. Jobs in the pending,
    holding, or timed execution states will retain the old RAD value
    on the job; however, when such a job becomes executable, the job
    is updated with the new RAD value.

    RAD is supported on AlphaServer GS series systems and starting
    from OpenVMS Version 8.4, support is extended to NUMA capable
    Integrity servers.
