--     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.
