/ENABLE=(keyword[,...])
    Enables alarms or audits for the specified events. To enable all
    system events and file access events, specify the keyword ALL.
    You must specify at least one keyword. You must also specify
    either the /ALARM or /AUDIT qualifier, or both, when you use the
    /ENABLE qualifier.
    The keywords that you can specify with either the /ENABLE or the
    /DISABLE qualifier are as follows:
    Keyword           Description
    ACCESS=(condition Specifies access events for all objects in
                      a class. (To audit a single object, use an
    [:access[,...]]   auditing ACE and enable the access control list
    [,...])           (ACL) category.)
                      HP recommends that when you enable auditing
                      conditionally, you enable it for all possible
                      forms of access because the system can check
                      access rights at several points during an
                      operation. (For example, a FAILURE might occur
                      on a read or write access check.)
                      See the HP OpenVMS Guide to System Security for
                      information about the various types of access
                      permitted on each class. (For example, the
                      Access keyword, CREATE, is not defined for FILE
                      objects.)

                      the ACCESS keyword.
    ALL               Specifies all system events and file access
                      events. It does not enable access events for
                      object classes other than FILE.

                                     is caused by an incomplete or
                                     syntactically incorrect argument
                                     being supplied to one of these
                                     system services by a piece of
