-- 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

-- 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.
