-- Simple casing functions
-- This package provides simple casing functions that do not require the
-- overhead of the full casing tables found in Ada.Characters.Handling.
-- Note: actual code is found in System.Case_Util, which is used internally
-- by the GNAT run time. Applications programs should always use this package
-- rather than using System.Case_Util directly.

pragma Pure (Case_Util);
pragma Elaborate_Body;
-- The elaborate body is because we have a dummy body to deal with bootstrap
-- path problems (we used to have a real body, and now we don't need it any
-- more, but the bootstrap requires that we have a dummy body, since otherwise
-- the old body gets picked up.
-- Note: all the following functions handle the full Latin-1 set
function To_Upper (A : Character) return Character
renames System.Case_Util.To_Upper;
-- Converts A to upper case if it is a lower case letter, otherwise
-- returns the input argument unchanged.
procedure To_Upper (A : in out String)
renames System.Case_Util.To_Upper;
-- Folds all characters of string A to upper csae
function To_Lower (A : Character) return Character
renames System.Case_Util.To_Lower;
-- Converts A to lower case if it is an upper case letter, otherwise
-- returns the input argument unchanged.

procedure To_Mixed (A : in out String)

-- character and any character after an underscore, which are
-- converted to upper case.
