  33 --                  OPERATORS ON 'SIZE TESTS, AND ADDED CHECK ON
  34 --                  REPRESENTATION CLAUSE.
  35 --     BCB 03/05/90 ADDED CALL TO LENGTH_CHECK TO VERIFY THAT THE SIZE
  36 --                  SPECIFICATION IS OBEYED.
  37 --     LDC 10/03/90 ADDED CASES FOR >=, /=, ASSIGNMENT, QUALIFICATION,
  38 --                  AND EXPLICIT CONVERSION.
  39 --     JRL 03/26/92 ELIMINATED REDUNDANT TESTING.
