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