-- 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

-- DISCLAIMER

-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED

--*
--
-- OBJECTIVE:
-- Check that a type that inherits abstract operations but
-- overrides each of these operations is not required to be
-- abstract, and that objects of the type and its class-wide type
-- may be declared and passed in calls to the overriding
-- subprograms.
--
-- TEST DESCRIPTION:
-- This test derives a type from the root abstract type available
-- in foundation F393A00. It declares subprograms as required by
-- the language to override the abstract subprograms, allowing the
-- derived type itself to be not abstract. It also declares
-- operations on the new type, as well as on the associated class-
-- wide type. The main program then uses two objects of the type
-- and two objects of the class-wide type as parameters for each of
-- the subprograms. Correct execution is determined by path
-- analysis and value checking.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- F393A00.A (foundation code)
-- C393A06.A
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 19 Dec 94 SAIC Removed RM references from objective text.
