-- OBJECTIVE:
--     CHECK THAT PUT FOR FIXED_IO RAISES CONSTRAINT_ERROR WHEN THE
--     VALUES SUPPLIED BY FORE, AFT, OR EXP ARE NEGATIVE OR GREATER
--     THAN FIELD'LAST WHEN FIELD'LAST < FIELD'BASE'LAST.  ALSO CHECK
--     THAT PUT FOR FIXED_IO RAISES CONSTRAINT_ERROR WHEN THE VALUE
--     OF ITEM IS OUTSIDE THE RANGE OF THE TYPE USED TO INSTANTIATE
--     FIXED_IO.
 
-- HISTORY:
--     JLH 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.
