+ --
+ -- OBJECTIVE:
+ --      Check that class-wide objects can be reassigned with objects from 
+ --      the same specific type used to initialize them.
+ --
+ -- TEST DESCRIPTION:
+ --      Define new objects of specific types from within a class. Reassign
+ --      previously declared class-wide objects with the new specific type 
+ --      objects. Check that new assignments were performed.
+ --
+ --      The particular root and extended types used in this abstraction are
+ --      defined in foundation code (F341A00.A), and are graphically displayed
+ --      as follows:
+ --
+ --           package Bank
+ --              type Account
+ --                  |
+ --                  |
+ --                  |
+ --               package Checking
+ --                  type Account
+ --                      |
+ --                      |
+ --                      | 
+ --                   package Interest_Checking
+ --                          type Account
+ --
+ -- TEST FILES:
+ --      This test depends on the following foundation code:
+ --
+ --         F341A00.A
+ --
+ --      The following files comprise this test:
