TITLE_and_SUBTITLE

 cDEC$ TITLE string
 cDEC$ SUBTITLE string

 The TITLE directive lets you specify a string and place it in the
 title field of a listing header.  Similarly, SUBTITLE lets you
 place a specified string in the subtitle field of a listing header.

 The "string" is a character constant containing up to 31 printable
 characters.

 To enable TITLE and SUBTITLE directives, you must specify the /LIST
 compiler option.

 When TITLE or SUBTITLE appears on a page of a listing file, the
 specified string appears in the listing header of the following
 page.

 If two or more of either directive appear on a page, the last
 directive is the one in effect for the following page.

 If either directive does not specify a string, no change occurs in
 the listing file header.

 For compatibility, !MS$TITLE:  and !MS$SUBTITLE:  can be used in
 place of cDEC$ TITLE and cDEC$ SUBTITLE.
