-- OBJECTIVE:

--     CHECK THAT FIXED_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 FIXED_IO.

-- APPLICABILITY CRITERIA:

--     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH SUPPORT

--     TEXT FILES.

-- HISTORY:

--     DWC 09/15/87  CREATED ORIGINAL TEST.

--     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. Corrected typo.
