The /SHOW qualifier determines which parts of the compilation listing  are
   created.   The  /LISTING  qualifier must have been specified for the /SHOW
   qualifier to have any effect.

   The format of the /SHOW qualifier is as follows:

      /[NO]SHOW[=({[NO]CDD_DEFINITIONS},...)]
                  {[NO]ENVIRONMENT    }
                  {[NO]INCLUDE        }
                  {[NO]MAP            }
                  {[NO]OVERRIDE       }
                  {ALL                }
                  {NONE               }

   where:

      CDD_DEFINITIONS controls whether the translation  of  a  CDD/Repository
                     record is displayed in the listing.

      ENVIRONMENT    lets you display all defaults that were in  effect  when
                     the program was compiled.

      INCLUDE        controls  whether  files  accessed  with  the   %INCLUDE
                     directive are displayed in the listing.

      MAP            determines whether the listing  contains  an  allocation
                     map.   The  allocation  map lists all program variables,
                     their size and their data type.

      OVERRIDE       helps you debug code by  disabling  the  effect  of  the
                     %NOLIST directive.

   The /NOSHOW qualifier causes the  compiler  to  display  only  the  source
   listing.

   /SHOW = ALL is the same as /SHOW = (CDD_DEFINITIONS, ENVIRONMENT, INCLUDE,
   MAP,  OVERRIDE).   /SHOW = NONE is the same as /NOSHOW.  /SHOW is the same
   as /SHOW = ALL.

   The default  is  /SHOW  =  (CDD_DEFINITIONS,  ENVIRONMENT,  INCLUDE,  MAP,
   NOOVERRIDE).
