VMS Help EDIT, /ACL, /CLASS, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    To edit the ACL for an object other than a file, specify the
    object class with the /CLASS qualifier. Specify one of the
    following classes:

    CAPABILITY           A system capability, such as the ability to
                         process vector instructions. Currently, the
                         only defined object name for the CAPABILITY
                         class is VECTOR, which governs the ability
                         of a subject to access a vector processor
                         on the system. Note that you must supply
