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

       /HOLD
       /NOHOLD (default)

    Controls whether or not the job is to be made available for
    immediate processing.

    If you specify the /HOLD qualifier, the job is not released for
    processing until you specifically release it with the /NOHOLD or
    the /RELEASE qualifier of the SET QUEUE/ENTRY command.
