/MAP[=option]
  /NOMAP         (D)

  Controls whether the compiler produces the following maps in the
  listing file:

      a.  data names, procedure names, file names, and their
          attributes
      b.  external references such as user-called routines or
          Run-Time Library routines

  You can control the format of the data name, procedure name, and
  file name maps in the listing file by specifying one or both of
  the following options:

  ALPHABETICAL        Produces an alphabetical list of map items
                      /MAP=ALPHABETICAL is the equivalent of /MAP.

  DECLARED            Produces a list of map items in the order
                      in which they were declared

  If you specify /MAP=(ALPHABETICAL,DECLARED), the compiler produces
  both alphabetical and declared map listings.

  The /MAP qualifier has no effect unless you also specify the /LIST
  qualifier.

  The default, /NOMAP, suppresses the creation of maps in the listing
  file.
