--     CHECK THAT RESETTING ONE OF A MULTIPLE OF INTERNAL FILES

--     ASSOCIATED WITH THE SAME EXTERNAL FILE HAS NO EFFECT ON ANY

--     OF THE OTHER INTERNAL FILES.

-- APPLICABILITY CRITERIA:

--     THIS TEST APPLIES ONLY TO IMPLEMENTATIONS WHICH SUPPORT MULTIPLE

--     INTERNAL FILES ASSOCIATED WITH THE SAME EXTERNAL FILE AND

--     RESETTING OF THESE MULTIPLE INTERNAL FILES FOR TEXT FILES.

-- HISTORY:

--     DLD 08/16/82

--     SPS 11/09/82

--     JBG 06/04/84

--     EG  11/19/85  MADE TEST INAPPLICABLE IF CREATE USE_ERROR.

--     TBN 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE RESULT WHEN

--                   FILES NOT SUPPORTED.

--     GMT 08/25/87  COMPLETELY REVISED.

--     EDS 12/01/97  ADD NAME_ERROR HANDLER TO OUTPUT NOT_APPLICABLE RESULT.

--     RLB 09/29/98  MADE MODIFICATION TO AVOID BUFFERING PROBLEMS.
