--*

-- OBJECTIVE:

--     CHECK THAT INTEGER_IO GET RAISES CONSTRAINT_ERROR IF THE

--     WIDTH PARAMETER IS NEGATIVE, IF THE WIDTH PARAMETER IS

--     GREATER THAN FIELD'LAST WHEN FIELD'LAST IS LESS THAN

--     INTEGER'LAST, OR THE VALUE READ IS OUT OF THE RANGE OF

--     THE ITEM PARAMETER BUT WITHIN THE RANGE OF INSTANTIATED

--     TYPE.

-- HISTORY:

--     SPS 10/04/82

--     DWC 09/09/87  ADDED CASES FOR WIDTH BEING GREATER THAN

--                   FIELD'LAST AND THE VALUE BEING READ IS OUT

--                   OF ITEM'S RANGE BUT WITHIN INSTANTIATED

--                   RANGE.

--     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.
