-- OBJECTIVE:
--      Check that a type derived in a public child inherits primitive 
--      operations from parent.  
--
-- TEST DESCRIPTION:
--      Declare a root record type with discriminant in a package 
--      specification. Declare a primitive subprogram for the type 
--      (foundation code).
--
--      Add a public child to the above package.  Derive a new type 
--      with constraint to the discriminant record type from the parent 
--      package.  Declare a new primitive subprogram to write to the child 
--      derived type.
--
--      Add a new public child to the above package.  This grandchild package
--      derives a new type using the record type from the above package.  
--      Declare a new primitive subprogram to write to the grandchild derived 
--      type.
--
--      In the main program, "with" the grandchild.  Access the inherited 
--      operations from grandparent, parent, and grandchild packages.
--
-- TEST FILES:
--      This test depends on the following foundation code:
