--
-- OBJECTIVE:
--      Check that a type extended in a client of a public child inherits 
--      primitive operations from parent.  
--
-- TEST DESCRIPTION:
--      Declare a root tagged type in a package specification. Declare two 
--      primitive subprograms for the type (foundation code).
--
--      Add a public child to the above package.  Extend the root type with 
--      a record extension in the specification.  Declare a new primitive 
--      subprogram to write to the child extension.
--
--      In the main program, "with" the child.  Declare an extension of
--      the child extension.  Access the primitive operations from both 
--      parent and child packages.
--
-- TEST FILES:
--      This test depends on the following foundation code:
--
--         FA11A00.A
--
--
-- CHANGE HISTORY:
--      06 Dec 94   SAIC    ACVC 2.0
--      20 Dec 94   SAIC    Moved declaration of Label_Widget to library level
--
