/sys$common/syshlp/helplib.hlb SET, ENTRY, Qualifiers, /HOLD  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /HOLD
       /NOHOLD

    Controls whether the job is to be made available for processing
    or held for processing later. If you specify the /HOLD qualifier,
    the job is not released for processing until you enter SET
    ENTRY/NOHOLD or SET ENTRY/RELEASE.

    You can use the /NOHOLD qualifier to release jobs that have been
    held for the following reasons:

    o  A job was submitted with the /HOLD qualifier.

    o  A completed job is being retained in a queue.

    o  A user-written symbiont has refused a job.

                                   NOTE

       Releasing or rescheduling a job before its submission time
       is not supported for security reasons. Therefore, if you set
       the system time to a future time and submit a job on a node
       where the queue manager is running, you cannot release or
       reschedule that job back to the present time if you reset
       the system time.

       For example, you can set the system time to a future time of
       January 1, 2020 and submit a job to run on January 9, 2020;
       however, if you set the system time back to the present time
       and try to release the job to the present time, the job will
       be released to January 1, 2020.

       This situation impacts the following qualifiers: /AFTER,
       /NOHOLD, and /RELEASE.
