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

    Allows jobs to be entered in the queue through PRINT or SUBMIT
    commands or as the result of requeue operations. To prevent
    jobs from being entered in the queue, use the /CLOSE qualifier.
    Whether a queue accepts or rejects new job entries is independent
    of the queue's state (such as paused, stopped, or stalled).
