-- OBJECTIVE:
--     CHECK THAT INTEGER_IO GET RAISES DATA_ERROR WHEN THE LEXICAL
--     ELEMENT IS NOT OF THE INTEGER TYPE EXPECTED.  CHECK THAT ITEM
--     IS UNAFFECTED AND READING CAN CONTINUE AFTER THE EXCEPTION
--     HAS BEEN HANDLED.

-- APPLICABILITY CRITERIA:
--     THIS TEST IS ONLY APPLICABLE TO IMPLEMENTATIONS WHICH
--     SUPPORT TEXT FILES.

-- HISTORY:
--     SPS 10/04/82
--     VKG 01/14/83
--     RJW 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     DWC 09/10/87  REMOVED UNNECCESSARY CODE, CORRECTED EXCEPTION
--                   HANDLING, AND CHECKED FOR USE_ERROR ON DELETE.
