       /CPUTIME=time

    Specifies a CPU time limit for the batch job. You can specify
    the time parameter as delta time, the value 0, INFINITE, or NONE.
    If the queue on which the job executes has a defined CPUMAXIMUM
    value, the smaller of the specified job and queue values is used.
    If the queue on which the job executes does not have a specified
    maximum CPU time limit, the smaller of the SUBMIT command and
    user authorization file (UAF) values is used. If the queue on
    which the job executes does not have a specified maximum CPU time
    limit and the UAF has a specified CPU time limit of NONE, either
    the value 0 or the keyword INFINITE allows unlimited CPU time. If
    you specify NONE, the specified queue or UAF value is used. CPU
    time values must be greater than or equal to the number specified
    by the system parameter PQL_MCPULM.

    For information on specifying time values, refer to the OpenVMS
    User's Manual or the online help topic DCL_Tips (subtopic Date_
    Time).
