-- OBJECTIVE:
--     CHECK THAT INTEGER_IO PUT RAISES CONSTRAINT_ERROR IF:
--        A) THE BASE IS OUTSIDE THE RANGE 2..16.
--        B) THE VALUE OF WIDTH IS NEGATIVE OR GREATER THAN FIELD'LAST,
--           WHEN FIELD'LAST < INTEGER'LAST.
--        C) THE VALUE OF ITEM IS OUTSIDE THE RANGE OF THE INSTANTIATED
--           TYPE.

-- HISTORY:
--     SPS 10/05/82
--     JBG 08/30/83
--     JLH 09/10/87  ADDED CASES FOR THE VALUE OF THE WIDTH BEING LESS
--                   THAN ZERO AND GREATER THAN FIELD'LAST AND CASES FOR
--                   THE VALUE OF ITEM OUTSIDE THE RANGE OF THE
--                   INSTANTIATED TYPE.
--     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.
