--
-- OBJECTIVE:
--      Check that type extended in a public child inherits primitive 
--      operations from its ancestor.  
--
-- 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.
--
--      Add a public grandchild to the above package.  Extend the extension of
--      the parent type with a record extension in the private part of the 
--      specification.  Declare a new primitive subprogram for this grandchild
--      extension.
--
--      In the main program, "with" the grandchild.  Access the primitive
--      operations from grandparent and parent package.
--
-- TEST FILES:
--      This test depends on the following foundation code:
