       /CPUTIME=n

    Specifies a CPU time limit for the batch job. Time can be
    specified as delta time, 0, NONE, or INFINITE. (For information
    on specifying time values, refer to the OpenVMS User's Manual or
    the online help topic DCL_Tips (subtopic Date_Time).)

    When you need less CPU time than authorized, use the /CPUTIME
    qualifier to override the base queue value established by the
    system manager or the value authorized in your UAF. Specify 0 or
    INFINITE to request an infinite amount of time. Specify NONE when
    you want the CPU time to default to your UAF value or the limit
    specified on the queue. Note that you cannot request more time
    than permitted by the base queue limits or your UAF.
