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

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

    Applies the specified protection to shareable name tables.

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

    o  Specify the access parameter as read (R),  write (W), create
       (C),  or delete (D).

    For more information on specifying protection codes, refer to the
    OpenVMS Guide to System Security.

    The /PROTECTION qualifier affects only shareable logical name
    tables; it does not affect process-private logical name tables.
