--     NON-LIMITED COMPONENT TYPES.
 
-- HISTORY:
--     JRK 09/22/86  CREATED ORIGINAL TEST.
--     BCB 11/13/87  CHANGED TEST SO AN OBJECT'S SIZE MAY BE LESS THAN
--                   THAT OF ITS TYPE.
--     RJW 08/21/89  MODIFIED CHECKS FOR SIZE.
--     PWN 01/31/95  REMOVED INCONSISTENCIES WITH ADA 9X.
