-- HISTORY:
--     JET 08/18/87 CREATED ORIGINAL TEST.
--     DHH 04/18/89 CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED
--                  OPERATORS ON 'SIZE TESTS, AND ADDED CHECK ON
--                  REPRESENTATION CLAUSE.
--     BCB 03/05/90 ADDED CALL TO LENGTH_CHECK TO VERIFY THAT THE SIZE
--                  SPECIFICATION IS OBEYED.
--     LDC 10/03/90 ADDED EXCEPTION HANDER FOR CHECK OF 'SUCC, 'PRED,
--                  ADDED CASES FOR >=, /=, ASSIGNMENT, QUALIFICATION,
