.DISPLAY_CHAPTER

   The .DISPLAY CHAPTER command allows you to specify the form that
   the numbering (or lettering) of chapters will take. The form you
   specify appears in the title, the page numbers, and the first
   character of header level numbers throughout the chapter. This
   command does not change any values; it affects only the way the
   values are displayed. (See also .CHAPTER and .NUMBER CHAPTER.)
