--*
--
-- OBJECTIVE:
-- Check that Ada.Strings.Unbounded versions of subprograms Translate
-- (procedure and function), Index, and Count, which use a
-- Maps.Character_Mapping_Function input parameter, produce correct
-- results.
--
-- TEST DESCRIPTION:
-- This test examines the operation of the four subprograms contained
-- in the Ada.Strings.Unbounded package that use a
-- Character_Mapping_Function parameter to provide the mapping
-- capability.
-- Two Character_Mapping_Function objects are defined that reference
-- subprograms contained in the Ada.Characters.Handling package;
-- To_Lower will return the lower-case form of the character provided
-- as the input parameter, To_Upper will return the upper-case form
-- of the character input parameter (provided there is an upper-case
-- form).
-- In several instances in this test, the character handling functions
-- are referenced directly in the parameter list of the subprograms
-- under test, demonstrating another form of expected common usage.
--
-- Results of all subprograms are compared with expected results.
--
-- This test, when taken in conjunction with tests CXA4010, CXA4011,
-- CXA4031, and CXA4032 will constitute a test of all the functionality
-- contained in package Ada.Strings.Unbounded. This test uses a variety
-- of the subprograms defined in the unbounded string package in ways
-- typical of common usage.
--
--
-- CHANGE HISTORY:
-- 21 Feb 95 SAIC Initial prerelease version
-- 21 Apr 95 SAIC Modified header commentary.
