-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the

--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR

--*
--
-- OBJECTIVE:
-- Check that for a call to a dispatching subprogram the subprogram
-- body which is executed is determined by the controlling tag for
-- the case where the call has dynamic tagged controlling operands
-- of the type T. Check for calls to these same subprograms where
-- the operands are of specific statically tagged types:
-- objects (declared or allocated), formal parameters, view
-- conversions, and function calls (both primitive and non-primitive).
--
-- TEST DESCRIPTION:
-- This test uses foundation F392C00 to test the usages of statically
-- tagged objects and values. This test is derived in part from
-- C392C05.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 24 Oct 95 SAIC Updated for ACVC 2.0.1
