VMS Help SET, QUEUE, Qualifiers, /RETAIN  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /RETAIN[=option]
       /NORETAIN

    Holds jobs in the queue in a retained status after they have
    executed. The /NORETAIN qualifier enables you to reset the queue
    to the default. Possible options are as follows:

    ALL     Holds all jobs in the queue after execution (default).
    ERROR   Holds in the queue only jobs that complete
            unsuccessfully.
