26
-- OBJECTIVE:
27
--      Check that a child unit can raise an exception that is declared in
28
--      parent.
29
--
30
-- TEST DESCRIPTION:
31
--      Declare a package which defines complex number abstraction with
32
--      user-defined exceptions (foundation code).
33
--
34
--      Add a public child package to the above package. Declare two
35
--      subprograms for the parent type.  Each of the subprograms raises a
36
--      different exception, based on the value of an input parameter.
37
--
38
--      Add a public child procedure to the foundation package.  This
39
--      procedure raises an exception based on the value of an input
40
--      parameter.
41
--
42
--      Add a public child function to the foundation package.  This
43
--      function raises an exception based on the value of an input
44
--      parameter.
45
--
46
--      In the main program, "with" the child packages, then check that
47
--      the exceptions are raised and handled as expected.  Ensure that
48
--      exceptions are:
49
--         1) raised in the public child package and handled/reraised to
50
--            be handled by the main program.
51
--         2) raised and handled locally in the public child package.
52
--         3) raised and handled locally by "others" in the public child
53
--            procedure.
54
--         4) raised in the public child function and propagated to the
55
--            main program.
