   /BENCHMARK=file-specification
   /NOBENCHMARK

   Specifies whether the benchmark file should be replaced or
   disassociated from a test description.

   The /BENCHMARK qualifier adds the specified benchmark file
   specification to the test description. This benchmark file
   supersedes any benchmark currently associated with the test
   description.

   The new file specification cannot contain a directory
   specification that points to the Digital Test Manager library.
   However, you can use DTM$LIB without a file name. The new file
   specification can specify a directory (other than the Digital Test
   Manager library) or a CMS library. The new file specification
   overrides any benchmark directory specified with an earlier
   CREATE TEST_DESCRIPTION command.

   The new file specification need not specify the same type of
   directory as the file specification you are overriding. For
   example, if you have been storing your benchmark files in a CMS
   library, you can specify a directory that is not a CMS library.

   If you specify a file name for a benchmark file that does not
   exist, Digital Test Manager treats the test like a new test when a
   collection that contains this test executes. When a benchmark
   file is created, it will have the file name you specify.

   The /NOBENCHMARK qualifier removes the benchmark file
   specification from the test description and replaces it with
   the default, test-name.BMK.
