--

-- 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.
