  26 -- OBJECTIVE:
  27 --      Check that formal parameters of a class-wide type can be passed
  28 --      values of any specific type within the class.
  29 --
  30 -- TEST DESCRIPTION:
  31 --      Define an object of a root tagged type and of various types derived
  32 --      from the root.  Define objects of the root class, and initialize them
  33 --      by parameter association of objects of the specific types (root and
  34 --      extended types) within the class.
  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
