   /COMPARISON_TYPE=keyword

   Specifies how the result and benchmark files are to be compared. A
   comparison type is not associated with the test description. The
   valid values for keyword are as follows:

     Keyword     Meaning

     CHARACTERS  Compares files character by character.

     RECORDS     Compares files record by record. This is the
                 default for noninteractive terminal tests.

     SCREENS     Compares files screen by screen; screens not
                 marked are not compared. This is the default for
                 interactive terminal and DECwindows tests.

   DECwindows tests can only use the SCREENS comparison type. The
   SCREENS comparison type is also the default comparison type for
   interactive terminal tests. If you specify the /COMPARISON_
   TYPE=SCREENS qualifier for a noninteractive test, this value is
   ignored.
