       /PRIORITY=n

    Requires OPER (operator) or ALTPRI (alter privilege) privilege
    to specify a priority greater than the queue's maximum scheduling
    priority.

    Specifies the job-scheduling priority for the batch job with
    respect to other jobs in the same queue. The value of n is an
    integer in the range of 0 to 255, where 0 is the lowest priority
    and 255 is the highest.

    The default value is the value of the system parameter DEFQUEPRI.
    No privilege is needed to set the priority lower than the queue's
    maximum scheduling priority, which is the value of the system
    parameter MAXQUEPRI.

    The /PRIORITY qualifier has no effect on the job's process
    execution priority. The job's process execution priority
    is determined by the base priority attribute of the
    INITIALIZE/QUEUE/BASE_PRIORITY command.
