17.2 Controlling the Compilation Listing
  The following compiler listing directives let you control the
  content and appearance of the compilation listing:

  .
        %TITLE places a title string on the first line of the listing
        header.
  .
        %SBTTL places a subtitle string on the second line of the
        listing header.
  .
        %IDENT places an identification string on the second line
        of the listing header and within the object module.
  .
        %PAGE causes BASIC to skip to top-of-form in the
        output listing.
  .
        %NOLIST causes BASIC to stop accumulating informa-
        tion for the output listing.
  .
        %LIST causes BASIC to resume accumulating informa-
        tion for the output listing.
  .
        %NOCROSS causes BASIC to stop accumulating cross-
        reference information for the output listing.
  .
        %CROSS causes BASIC to resume accumulating cross-
        reference information for the output listing.

  These directives are described in the following sections.
The listing control directives have no effect if no source pro-
  gram listing is being produced. Similarly, the %CROSS and
  %NOCROSS directives have no effect if no cross-reference
  listing is being produced. However, the %IDENT directive
  places the specified text in the object module whether or not a
  listing is produced.
