--
-- OBJECTIVE:
-- Check that formal parameters of a class-wide type can be passed
-- values of any specific type within the class.
--
-- TEST DESCRIPTION:
-- Define an object of a root tagged type and of various types derived
-- from the root. Define objects of the root class, and initialize them
-- by parameter association of objects of the specific types (root and
-- extended types) within the class.
--
-- 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:
--
-- => C341A01.A
