1    /CONFIRM

    Controls whether CMS prompts you for confirmation before each
    transaction.

    When you specify /CONFIRM and run CMS in interactive mode, CMS
    prompts you for confirmation. If you type YES, ALL, TRUE, or 1,
    CMS executes the transaction.  If you type NO, QUIT, FALSE, 0,
    or press RETURN or CTRL/Z, no action is performed. If you type
    any other character, CMS continues to prompt until you type an
    acceptable response.

    CMS does not prompt for confirmation in batch mode.

2    /LIBRARY[=directory-specification]

    Identifies a valid CMS library that is the location of the element
    specified by the old-element-expression parameter. When you
    specify an alternative library, the new-element-name parameter is
    optional. If you do not specify a value for /LIBRARY, the current
    CMS library is used.

3    /LOG (D)

    Controls whether CMS displays success and informational messages
    on the default output device. By default, if the command executes
    successfully, CMS displays a success message. If you specify
    /NOLOG, success and informational messages are suppressed. Any
    warning, error, or fatal error messages are displayed regardless
    of whether /LOG or /NOLOG is specified.

4    /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 (ELEMENT, GROUP)
       ELEMENT (D)
       NOELEMENT
       GROUP (D)
       NOGROUP
       NONE--equivalent to (NOELEMENT, NOGROUP)

    You can specify either ALL or NONE, or any combination of the
    [NO]ELEMENT and [NO]GROUP keywords.

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