-- CXA4012.A---- 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 the types, operations, and other entities defined within-- the package Ada.Strings.Wide_Maps are available and produce correct-- results.---- TEST DESCRIPTION:-- This test demonstrates the availability and function of the types and-- operations defined in package Ada.Strings.Wide_Maps. It demonstrates-- the use of these types and functions as they would be used in common-- programming practice.-- Wide_Character set creation, assignment, and comparison are evaluated-- in this test. Each of the functions provided in package-- Ada.Strings.Wide_Maps is utilized in creating or manipulating set-- objects, and the function results are evaluated for correctness.-- Wide_Character sequences are examined using the functions provided for -- manipulating objects of this type. Likewise, Wide_Character maps are-- created, and their contents evaluated. Exception raising conditions-- from the function To_Mapping are also created.-- Note: Throughout this test, the set logical operators are printed in-- capital letters to enhance their visibility.---- -- CHANGE HISTORY:-- 06 Dec 94 SAIC ACVC 2.0-- 01 Nov 95 SAIC Update and repair for ACVC 2.0.1.-- --!with Ada.Characters.Handling;with Ada.Strings.Wide_Maps;package CXA40120 is function Equiv (Ch : Character) return Wide_Character; function Equiv (Str : String) return Ada.Strings.Wide_Maps.Wide_Character_Sequence; function X_Map(From : Wide_Character) return Wide_Character;end CXA40120;package body CXA40120 is -- The following two functions are used to translate character and string -- values to "Wide" values.
