--     CHECK THAT WHEN A SIZE SPECIFICATION IS GIVEN FOR AN

--     INTEGER TYPE, THEN OPERATIONS ON VALUES OF SUCH A TYPE

--     WITH THE SMALLEST APPROPRIATE SIGNED SIZE ARE NOT

--     AFFECTED BY THE REPRESENTATION CLAUSE.

-- HISTORY:

--     JET 08/12/87  CREATED ORIGINAL TEST.

--     DHH 04/10/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED

--                   SIZE CLAUSE VALUE TO 7, CHANGED OPERATOR ON 'SIZE

--                   CHECKS AND ADDED REPRESENTAION CLAUSE CHECK.

--     RJW 03/28/90  REMOVED ERRONEOUS REFERENCES TO LENGTH_CHECK.

--     JRL 03/27/92  ELIMINATED REDUNDANT TESTING.
