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

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

    Specifies the protection of the queue:

    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. The default
    protection is (SYSTEM:M, OWNER:D, GROUP:R, WORLD:S). 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 chapter on queues in the OpenVMS System Manager's Manual.
