States whether output files (benchmark, difference, and result
   files) exist for result descriptions with the successful
   comparison status. The default is to display information for the
   current result description. If the benchmark file exists, its file
   specification is displayed.

   If you include an output file qualifier with the /SUCCESSFUL
   qualifier, the specified output files are displayed for result
   descriptions with the successful comparison status. If a test
   is successful, it has a benchmark file. Its result file was
   deleted and no difference file was created. You cannot specify
   a comparison status qualifier with a result description name
   parameter; a result description expression is required.
