-- OBJECTIVE:
--     CHECK WHETHER  READ  FOR A SEQUENTIAL FILE RAISES  DATA_ERROR OR
--     CONSTRAINT_ERROR WHEN AN ELEMENT IS READ THAT IS OUTSIDE THE

--     TYPE, AND CHECK THAT READING CAN CONTINUE AFTER THE EXCEPTION
--     HAS BEEN HANDLED.

--          A) CHECK ENUMERATION TYPE.

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

--     SPS 09/28/82
--     JBG 06/04/84
--     TBN 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE

--     GMT 07/24/87  RENAMED FROM CE2210A.ADA AND REMOVED THE USE OF
