-- OBJECTIVE:
--      Check that a child unit can raise an exception that is declared in 
--      parent.                
--
-- TEST DESCRIPTION:
--      Declare a package which defines complex number abstraction with
--      user-defined exceptions (foundation code).
--
--      Add a public child package to the above package. Declare two 
--      subprograms for the parent type.  Each of the subprograms raises a 
--      different exception, based on the value of an input parameter.
--
--      Add a public child procedure to the foundation package.  This
--      procedure raises an exception based on the value of an input 
--      parameter.
--
--      Add a public child function to the foundation package.  This
--      function raises an exception based on the value of an input 
--      parameter.
--
--      In the main program, "with" the child packages, then check that
--      the exceptions are raised and handled as expected.  Ensure that
--      exceptions are:
--         1) raised in the public child package and handled/reraised to
--            be handled by the main program.
--         2) raised and handled locally in the public child package.
--         3) raised and handled locally by "others" in the public child 
--            procedure.
--         4) raised in the public child function and propagated to the
--            main program.
