-- OBJECTIVE:
--     CHECK THAT FLOAT_IO GET RAISES CONSTRAINT_ERROR WHEN THE VALUE
--     SUPPLIED BY WIDTH IS NEGATIVE, WIDTH IS GREATER THAN FIELD'LAST
--     WHEN FIELD'LAST IS LESS THAN INTEGER'LAST, OR THE VALUE READ IS
--     OUT OF RANGE OF THE ITEM PARAMETER, BUT WITHIN THE RANGE OF THE
--     SUBTYPE USED TO INSTANTIATE FLOAT_IO.
 
-- APPLICABILITY CRITERIA:
--     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH
--     SUPPORT TEXT FILES.
 
-- HISTORY:
--     SPS 09/07/82
--     JBG 08/30/83
--     DWC 09/11/87  SPLIT CASE FOR FIXED_IO INTO CE3804P.ADA AND
--                   CORRECTED EXCEPTION HANDLING.
--     JRL 06/07/96  Added call to Ident_Int in expressions involving
--                   Field'Last, to make the expressions non-static and
--                   prevent compile-time rejection.
