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

--*
--
-- OBJECTIVE:
-- Check that the function "-", To_Ranges, To_Domain, and To_Range are
-- available in the package Ada.Strings.Maps, and that they produce
-- correct results based on the Character_Set/Character_Mapping input
-- provided.
--
-- TEST DESCRIPTION:
-- This test examines the operation of four functions from within the
-- Ada.Strings.Maps package. A variety of Character_Sequence,
-- Character_Set, and Character_Mapping objects are created and
-- initialized for use with these functions. In each subtest of
-- function operation, specific inputs are provided to the functions as
-- input parameters, and the results are evaluated against expected
-- values. Wherever appropriate, additional characteristics of the
-- function results are verified against the prescribed result
-- characteristics.
--
--
-- CHANGE HISTORY:
-- 03 Feb 95 SAIC Initial prerelease version
-- 10 Mar 95 SAIC Incorporated reviewer comments.
-- 15 Apr 96 SAIC Incorporated reviewer comments for ACVC 2.1.
-- 05 Oct 96 SAIC Incorporated reviewer comments for ACVC 2.1.
