-- 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

-- DISCLAIMER

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

--*
--
-- OBJECTIVE:
-- Check that the subprograms defined in package Ada.Strings.Fixed are
-- available, and that they produce correct results. Specifically,
-- check the subprograms Delete, Head, Insert, Overwrite, Replace_Slice,
-- Tail, Trim, and "*".
--
-- TEST DESCRIPTION:
-- This test, when combined with tests CXA4002-4 will provide coverage
-- of the functionality found in Ada.Strings.Fixed.
-- This test contains many small, specific test cases, situations that
-- although common in user environments, are often difficult to generate
-- in large numbers in a application-based test. They represent
-- individual usage paradigms in-the-small.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 11 Apr 95 SAIC Corrected acceptance conditions of certain
-- subtests.
-- 06 Nov 95 SAIC Fixed bugs for ACVC 2.0.1.
-- 22 Feb 01 PHL Check that the lower bound of the result is 1.
-- 13 Mar 01 RLB Fixed a couple of ACATS style violations;
-- removed pointless checks of procedures.
-- Added checks of other functions. These changes
-- were made to test Defect Report 8652/0049, as
-- reflected in Technical Corrigendum 1.
