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

       /PROTECTION=(ownership[:access],...)

    Requires OPER (operator) privilege to control access to the
    queue.

    Specifies the protection of the queue. The following rules apply:

    o  Specify the ownership parameter as system (S),  owner (O),
       group (G),  or world (W).

    o  Specify the access parameter as read (R),  submit (S), manage
       (M),  or delete (D). A null access specification means no
       access.

    If you include only one protection code, you can omit the
    parentheses.

    For more information on specifying protection codes, refer to
    the OpenVMS Guide to System Security. For more information on
    controlling queue operations through UIC-based protection, refer
    to the OpenVMS System Manager's Manual.
