--*
--
-- OBJECTIVE:
-- Check that a dispatching call to an abstract subprogram invokes
-- the correct subprogram body of a descendant type according to
-- the controlling tag.
-- Check that a subprogram can be declared with formal parameters
-- and result that are of an abstract type's associated class-wide
-- type and that such subprograms can be called. 3.4.1(4)
--
-- TEST DESCRIPTION:
-- This test declares several objects of types derived from the
-- abstract type as defined in the foundation F393A00. It then calls
-- various dispatching and class-wide subprograms using those objects.
-- The packages in F393A00 are instrumented to trace the flow of
-- execution.
-- The test checks for the correct order of execution, as expected
-- by the various calls.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- F393A00.A (foundation code)
-- C393A02.A
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 19 Dec 94 SAIC Removed RM references from objective text.
-- 05 APR 96 SAIC Update RM references for 2.1
