-- OBJECTIVE:

--     CHECK THAT INCOMPATIBLE FIXED POINT CONSTRAINTS RAISE

--     APPROPRIATE EXCEPTIONS.

-- HISTORY:

--     RJK 05/17/83  CREATED ORIGINAL TEST.

--     PWB 02/03/86  CORRECTED TEST ERROR:

--                   ADDED POSSIBLITY OF NUMERIC_ERROR

--                   IN DECLARATIONS OF SFX3 AND SFX4.

--     BCB 10/21/87  CHANGED HEADER TO STANDARD FORMAT.  CHANGED RANGE

--                   CONSTRAINTS OF SUBTYPE SFX1.  CHANGED UPPER BOUND

--                   OF THE CONSTRAINT OF SFX4.  CHANGED RANGE

--                   CONSTRAINTS OF FIX.

--     JRL 03/30/93  REMOVED NUMERIC_ERROR FROM TEST.

--     PWN 10/27/95  REMOVED OUT OF RANGE STATIC VALUE CHECKS.

--     EDS 07/16/98  AVOID OPTIMIZATION
