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.

/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 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.

/REMOVE_CONTENTS
   Controls whether CMS removes elements and groups from the specified
   group prior to deleting the group. When /REMOVE_CONTENTS is
   specified CMS displays an informational message for each element or
   group that is removed from the group.
