--     BOUNDED AND THE GIVEN COLUMN POSITION EXCEEDS THE LINE LENGTH
--     FOR FILES OF MODE OUT_FILE.

-- APPLICABILITY CRITERIA:
--     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH SUPPORT
--     CREATION OF TEMPORARY TEXT FILES WITH OUT_FILE MODE.

-- HISTORY:
--     ABW 08/26/82
--     TBN 11/10/86  REVISED TEST TO OUTPUT A NOT_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     JLH 08/31/87  CORRECTD EXCEPTION HANDLING AND ADDED NEW CASES
--                   FOR OBJECTIVE.
