--
-- Grant of Unlimited Rights
--
-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- 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
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that structures nesting discriminated records as
-- components in record extension are correctly supported. Check
-- for this using limited private structures.
-- Check that record extensions inherit all the visible components
-- of their ancestor types.
-- Check that discriminants are correctly inherited.
--
-- TEST DESCRIPTION:
-- This test defines a textbook object, a serial number plaque.
-- This object is used in each of several other structures modeled
-- after those used in an existing antenna modeling software system.
-- Record types discriminated and undiscriminated are nested to
-- produce a layered design. Some parametrization is programmatic;
-- some parametrization is data-driven.
--
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 19 Dec 94 SAIC Removed RM references from objective text.
-- 19 Apr 95 SAIC Added "limited" to full type def of "Object"
