       /TIME_LIMIT=limit

    Specifies the maximum amount of CPU time (in delta time) a
    created process can use. CPU time is allocated to the created
    process in units of 10 milliseconds. When it has exhausted its
    CPU time limit quota, the created process is deleted.

    If this quota is not specified and the created process is a
    detached process, the detached process receives a default value
    of zero, that is, unlimited CPU time.

    If this quota is not specified and the created process is a
    subprocess, the subprocess receives half the CPU time limit quota
    of the creating process.

    If this quota is specified as zero, the created process has
    unlimited CPU time providing that the creating process also has
    unlimited CPU time. If, however, the creating process does not
    have unlimited CPU time, the created process receives half the
    CPU time limit quota of the creating process.

    The CPU time limit quota is a consumable quota; that is, the
    amount of CPU time used by the created process is not returned to
    the creating process when the created process is deleted.

    If you restrict CPU time for a process, specify the time limit
    according to the rules for specifying delta time values, as given
    in the OpenVMS User's Manual or the online help topic DCL_Tips
    (subtopic Date_Time).
