  25 -- OBJECTIVE:
  26 --     CHECK THAT FLOAT_IO GET RAISES CONSTRAINT_ERROR WHEN THE VALUE
  27 --     SUPPLIED BY WIDTH IS NEGATIVE, WIDTH IS GREATER THAN FIELD'LAST
  28 --     WHEN FIELD'LAST IS LESS THAN INTEGER'LAST, OR THE VALUE READ IS
  29 --     OUT OF RANGE OF THE ITEM PARAMETER, BUT WITHIN THE RANGE OF THE
  30 --     SUBTYPE USED TO INSTANTIATE FLOAT_IO.
  31
  32 -- APPLICABILITY CRITERIA:
  33 --     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH
  34 --     SUPPORT TEXT FILES.

  36 -- HISTORY:
  37 --     SPS 09/07/82
  38 --     JBG 08/30/83
  39 --     DWC 09/11/87  SPLIT CASE FOR FIXED_IO INTO CE3804P.ADA AND
  40 --                   CORRECTED EXCEPTION HANDLING.
  41 --     JRL 06/07/96  Added call to Ident_Int in expressions involving
  42 --                   Field'Last, to make the expressions non-static and
  43 --                   prevent compile-time rejection.
