-- 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,
-- AND EXPLICIT CONVERSION.
-- WMC 03/27/92 ELIMINATED TEST REDUNDANCIES.
