 --
 -- OBJECTIVE:
 --      Check that for a nonabstract private extension, any inherited
 --      abstract subprograms can be overridden in the private part of
 --      the immediately enclosing package and that calls can be made to
 --      private dispatching operations.
 --
 -- TEST DESCRIPTION:
 --      This test builds an additional layer upon the foundation code to
 --      provide the required "hidden" dispatching operation.  The procedure
 --      Swap, a private subprogram, should be called by dispatch.
 --
 -- TEST FILES:
 --      The following files comprise this test:
 --
 --         F393A00.A   (foundation code)
 --         C393A05.A
 --

-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
