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

       /PRIVILEGES={CURRENT|AUTHORIZED}

    Determines whether the subprocess inherits the current
    process's current or authorized privileges as its authorized
    privileges. By default, the authorized privilege mask for
    the subprocess is taken from the current privileges of its
    creator. (This corresponds to /PRIVILEGES=CURRENT.) If the
    /PRIVILEGES=AUTHORIZED qualifier is specified, the subprocess's
    authorized privileges are taken from the creator's authorized
    privileges.
