-- OBJECTIVE:
--     FOR DIRECT ACCESS FILES, CHECK THAT A WRITE TO A POSITION
--     GREATER THAN THE CURRENT END POSITION CAUSES THE WRITE
--     POSITION AND THE FILE SIZE TO BE INCREMENTED.

--          1) CHECK FILES OF MODE INOUT_FILE.

-- APPLICABILITY CRITERIA:
--     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH SUPPORT
--     CREATE WITH INOUT_FILE MODE FOR DIRECT FILES.

-- HISTORY:
--     ABW 08/27/82
--     SPS 11/09/82
--     SPS 03/18/83
--     EG  05/16/85
--     TBN 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     GMT 08/05/87  REVISED EXCEPTION HANDLING, ADDED CHECK FOR WRITE
--                   USING TO, AND MOVED OUT_FILE CASE TO CE2409B.ADA.
