/SHOW=(option[,...])
     /SHOW=SOURCE (D)

  Used with the /LIST qualifier to set or cancel specific listing
  options.  You can select the following options:

  ALL               Print all listing information.

  [NO]BRIEF         Print a brief symbol table, listing only those
                    identifiers that are referenced in the program.

  [NO]CROSS_REFERENCE
                    Specifies whether the compiler generates
                    cross-references.  If you specify
                    /SHOW=CROSS_REFERENCE, the compiler lists, for
                    each variable referenced in the procedure, the
                    line numbers of the lines on which the variable
                    is referenced.

                    You may use /SHOW=CROSS_REFERENCE with
                    /SHOW=SYMBOLS.  Otherwise, specifying
                    /SHOW=CROSS_REFERENCE also gives you /SHOW=BRIEF.
                    To obtain any type of listing, you must specify
                    /LIST.  /SHOW=CROSS_REFERENCE is the same as
                    specifying /[NO]CROSS_REFERENCE.  (D =
                    NOCROSS_REFERENCE)

  [NO]DICTIONARY    Print/do not print Common Data Dictionary
                    definitions.  (D = NODICTIONARY)

  [NO]EXPANSION     Print/do not print macro expansions.
                    (D = NOEXPANSION)

  [NO]FULLPATH      Print/do not print the location of included
                    headers in the listing file and as informational
                    messages.  The locations will not include any
                    defined logicals, but will be the actual disk and
                    directory locations even if any logicals were
                    defined with /TRANSLATION_ATTRIBUTE=CONCEALED.
                    (D = NOFULLPATH)

  [NO]HEADER        Print/do not print header lines at the top of
                    each page.  (D = HEADER)

  [NO]INCLUDE       Print/do not print contents of #include files.
                    (D = NOINCLUDE)

  [NO]MESSAGES      Print/do not print a list of all messages that
                    are in effect at compilation (based on the
                    settings of /STANDARD, /WARNINGS, and #pragma
                    message).  (D = NOMESSAGES)

  NONE              Print no listing information.

  [NO]SOURCE        Print/do not print source file statements.
                    (D = SOURCE)

  [NO]STATISTICS    Print/do not print compiler performance
                    statistics.  (D = NOSTATISTICS)

  [NO]SYMBOLS       Print/do not print symbol table information in
                    the listing file.  (D = NOSYMBOLS)
