/SHOW=(option[,...]) D=/SHO=(NOIN,MAP)

 /[NO]SHOW

 Controls whether optionally listed source lines and a symbol map
 appear in the source listing.  (Optionally listed source lines are
 text-module source lines and preprocessor-generated source lines.)

 For the /SHOW qualifier to take effect, you must specify the /LIST
 qualifier.

 [NO]INCLUDE
   Controls whether the source lines from any file or text module
   specified by INCLUDE statements are included in the source
   listing.

 [NO]MAP
   Controls whether the symbol map is included in the listing file.

 ALL
   Requests that all optionally listed source lines and a symbol map
   be included in the listing file.  This is the same as specifying
   /SHOW without any arguments.

 NONE
   Requests that no optionally listed source lines or a symbol map
   be included in the listing file.  This is the same as specifying
   /NOSHOW.

 The /SHOW qualifier defaults are NOINCLUDE and MAP.
