--*
--
-- OBJECTIVE:
-- Check that versions of Ada.Strings.Bounded subprograms Translate,
-- (procedure and function), Index, and Count, which use the
-- Maps.Character_Mapping_Function input parameter, produce correct
-- results.
--
-- TEST DESCRIPTION:
-- This test examines the operation of several subprograms from within
-- the Ada.Strings.Bounded package that use the
-- Character_Mapping_Function mapping parameter to provide a mapping
-- capability.
--
-- Two functions are defined to provide the mapping. Access values
-- are defined to refer to these functions. One of the functions will
-- map upper case characters in the range 'A'..'Z' to their lower case
-- counterparts, while the other function will map lower case characters
-- ('a'..'z', or a character whose position is in one of the ranges
-- 223..246 or 248..255, provided the character has an upper case form)
-- to their upper case form.
--
-- Function Index uses the mapping function access value to map the input
-- string prior to searching for the appropriate index value to return.
-- Function Count uses the mapping function access value to map the input
-- string prior to counting the occurrences of the pattern string.
-- Both the Procedure and Function version of Translate use the mapping
-- function access value to perform the translation.
--
--
-- CHANGE HISTORY:
-- 16 FEB 95 SAIC Initial prerelease version
-- 17 Jul 95 SAIC Incorporated reviewer comments. Replaced two
-- internally declared functions with two library
-- level functions to eliminate accessibility
-- problems.
--
--!
-- Function CXA4027_0 will return the lower case form of
-- the character input if it is in upper case, and return the input
-- character otherwise.
