26 -- OBJECTIVE:
27 -- Check that class-wide objects can be reassigned with objects from
28 -- the same specific type used to initialize them.
29 --
30 -- TEST DESCRIPTION:
31 -- Define new objects of specific types from within a class. Reassign
32 -- previously declared class-wide objects with the new specific type
33 -- objects. Check that new assignments were performed.
34 --
35 -- The particular root and extended types used in this abstraction are
36 -- defined in foundation code (F341A00.A), and are graphically displayed
37 -- as follows:
38 --
39 -- package Bank
40 -- type Account
41 -- |
42 -- |
43 -- |
44 -- package Checking
45 -- type Account
46 -- |
47 -- |
48 -- |
49 -- package Interest_Checking
50 -- type Account
51 --
52 -- TEST FILES:
53 -- This test depends on the following foundation code:
