26 -- OBJECTIVE:
27 -- Check that class-wide objects can be initialized using allocation.
28 --
29 -- TEST DESCRIPTION:
30 -- Declare access types that refer to class-wide types, one with basis
31 -- of the root type, another with basis of a type extended from the root.
32 -- Declare objects of these access types, and allocate class-wide
33 -- objects, initialized to values of specific types within the particular
34 -- classes.
35 --
36 -- The particular root and extended types used in this abstraction are
37 -- defined in foundation code (F341A00.A), and are graphically displayed
38 -- as follows:
39 --
40 -- package Bank
41 -- type Account
42 -- |
43 -- |
44 -- |
45 -- package Checking
46 -- type Account
47 -- |
48 -- |
49 -- |
50 -- package Interest_Checking
51 -- type Account
52 --
