--
-- 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.
