--     THE EXPRESSIONS IN THE PARENT TYPE.

-- HISTORY:
--     RJW 06/19/86  CREATED ORIGINAL TEST.
--     BCB 08/19/87  CHANGED HEADER TO STANDARD HEADER FORMAT.  CHANGED
--                   PACKAGE B SO WOULD HAVE ONE CASE WHERE DEFAULT IS
--                   DECLARED BEFORE THE DERIVED TYPE DECLARATION.
