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 only group names.

3    /CONTENTS[=n]

    Lists the group name and creation remark, along with the names of
    any elements or groups contained within the specified group.

    You can specify an integer value (n) that directs CMS to display
    nested groups up or down to and including the level indicated by
    n. When you specify /CONTENTS without a value, CMS displays one
    level of contents. You can also specify /CONTENTS=ALL to display
    all levels of contained groups.

4    /FULL

    The /FULL qualifier displays the group name, creation remark, and
    read-only attribute (if established) for each group.

5    /INTERMEDIATE

    The /INTERMEDIATE qualifier displays the name and creation remark
    associated with each group.

6    /OCCLUDE[=option,...]

    Controls whether CMS selects the first instance of the specified
    object, or all instances of the specified object in the library
    search list. The options field contains one or more keywords
    associated with the name of the object. The options field can
    contain the following keywords:

       ALL--equivalent to GROUP
       GROUP (D)
       NOGROUP
       NONE--equivalent to NOGROUP

    You can specify either ALL, NONE, or the [NO]GROUP keyword.

    By default, CMS performs occlusion for all objects; that is, CMS
    selects only the first occurrence of a specified object.

7    /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.
