DEFQUEPRI establishes the scheduling priority for jobs entered
    in batch and output (printer, server, and terminal) queues when
    no explicit scheduling priority is specified by the submitter.
    The value of this parameter can range from 0 to 255; the default
    value is 100.

    The value of DEFQUEPRI should be less than or equal to MAXQUEPRI.

                                   NOTE

       DEFQUEPRI refers to relative queue scheduling priority, not
       the execution priority of the job.

    DEFQUEPRI is a DYNAMIC parameter.
