--*
--
-- OBJECTIVE:
--      Check that adjust is called on the value of a constant object created
--      by the evaluation of a generic association for a formal object of
--      mode in.
--
--      Check that those values are also subsequently finalized.
--
-- TEST DESCRIPTION:
--      Create a backdrop of a controlled type sufficient to check that the
--      correct operations get called at appropriate times.  Create a generic
--      unit that takes a formal parameter of a formal type.  Create instances
--      of this generic using various "levels" of the controlled type.  Check
--      the same case for a generic child unit.
--
--      The cases tested are where the type of the formal object is:
--        a visible classwide type  : CC40001_2
--        a formal private type     : CC40001_3
--        a formal tagged type      : CC40001_4
--
--      To more fully take advantage of the features of the language, and
--      present a test which is "user oriented" this test utilizes multiple
--      aspects of the language in combination.  Using Ada.Strings.Unbounded
--      in combination with Ada.Finalization and Ada.Calendar to build layers
--      of an object oriented system will likely be very common in actual
--      practice.  A common paradigm in the language will also be the use of
--      a parent package defining "basic" tagged types, and child packages
--      will expand on those types via derivation.  The model used in this
--      test is a simple type containing a character identity (used in the
--      identity).  The next level of type add a timestamp.  Further levels
--      might add location information, etc. however for the purposes of this
--      test we stop at the second layer, as it is sufficient to test the
--      stated objective.
--
--
-- CHANGE HISTORY:
--      06 FEB 96   SAIC   Initial version
--      30 APR 96   SAIC   Added finalization checks for 2.1
--      13 FEB 97   PWB.CTA  Moved global objects into bodies, after Initialize
--                         body is elaborated; counted finalizations correctly.
