Qualifiers

/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.

   The /NOCONFIRM qualifier does not override the confirmation prompt
   issued when you unreserve a concurrent reservation or when you
   cancel another user's reservation.

/DELETE[=file-specification]
   Controls whether all versions of the unreserved file are deleted.
   If you omit /DELETE, the files are not deleted. If you specify
   /DELETE without a file specification, all versions of the
   unreserved files are deleted from your current directory. The
   file specification allows you to specify a different location and
   the name of the file to be deleted.

/GENERATION=generation-expression
   Specifies which reserved generation of the element is to be
   unreserved. If you have more than one reservation of the same
   element generation, you must use the /IDENTIFICATION_NUMBER
   qualifier to unreserve the reservation.

/IDENTIFICATION_NUMBER=n
   Specifies which reservation is to be unreserved. This qualifier
   is required when you have multiple reservations of the same
   generation of an element. This qualifier is also required
   when multiple users have reserved the same generation of an
   element and you have BYPASS privilege or have been granted
   BYPASS access to the element by an access control list entry.
   /IDENTIFICATION_NUMBER can be used instead of /GENERATION
   when you have multiple reservations. Use the SHOW RESERVATIONS
   command to determine the identification number of each
   reservation. The identification number appears in
   parentheses at the beginning of each line.

/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.

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

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

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