-- 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.
