--     ARE NOT AFFECTED BY THE REPRESENTATION CLAUSE.
 
-- HISTORY:
--     JET 08/06/87  CREATED ORIGINAL TEST.
--     DHH 04/06/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED
--                   SIZE CLAUSE VALUE TO 9, AND ADDED REPRESENTAION
--                   CLAUSE CHECK.
--     JRL 03/27/92  ELIMINATED REDUNDANT TESTING.
