--     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.
