--*
--
-- 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
