States whether output files (benchmark, difference, and result
   files) exist for result descriptions with the unsuccessful
   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 /UNSUCCESSFUL
   qualifier, the specified output files are displayed for result
   descriptions with the unsuccessful comparison status. (If a test
   is unsuccessful, it has benchmark, result, and difference files.)
   You cannot specify a comparison status qualifier with a result
   description name parameter; a result description expression is
   required.
