1    /APPEND

    Controls whether CMS appends the command output to an existing
    file, or creates a new file. If you specify /APPEND and the output
    file does not exist, CMS creates a new file. If you do not provide
    an output file specification (see the description for /OUTPUT),
    the output is appended to SYS$OUTPUT.

2    /BRIEF

    The /BRIEF qualifier displays the directory specification (and
    does not lock the library) even if the default library is locked
    by another user. However, if the library needs recovery, it is
    not detected until another operation is performed.

3    /FULL

    The /FULL qualifier displays the current library directory
    specification, the number of elements, groups, classes,
    reservations, concurrent replacements, reviews pending, and
    the current reference copy directory specification, if any.

4    /INTERMEDIATE

    The /INTERMEDIATE qualifier displays the directory specification
    of the current CMS library.

5    /OUTPUT[=file-specification]

    Directs CMS to write output to the specified file, except for any
    warning and error messages, which are written to SYS$OUTPUT and
    SYS$ERROR. CMS creates a new file if you do not specify /APPEND.
    If you omit the /OUTPUT qualifier (or if you specify /OUTPUT
    but do not provide a file specification), CMS directs output to
    the default output device (SYS$OUTPUT). If you omit either the
    file name or the file type component, CMS supplies the missing
    component from the default specification.
