+ -- 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
