Section 13,1,4: 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 that you specify can consist of up to 31 printable
 characters and must be delimited by apostrophes.

 In addition to the compiler-directive syntax rules, the TITLE and
 SUBTITLE directives have the following specific rules:

  -  To enable TITLE and SUBTITLE directives, you must specify the
     -V 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.
