Как получить информацию о локальных настройках системы?

Delphi имеет функцию GetLocaleInfo, которая позволяет получать различную информацию о локальных настройках, таких как системный язык, символ валюты, количество десятичных знаков и т.д.

Далее приведена функция, которая возвращает значение в зависимости от параметра "flag":

........ 
function TForm1.GetLocaleInformation(Flag: Integer): String; 
var 
  pcLCA:    Array[0..20] of Char; 
begin 
  if( GetLocaleInfo(LOCALE_SYSTEM_DEFAULT,Flag,pcLCA,19) <= 0 ) then begin 
    pcLCA[0] := #0; 
  end; 
  Result := pcLCA; 
end; 
........ 

Пример использования функции:

........ 
procedure TForm1.Button1Click(Sender: TObject); 
begin 
  ShowMessage(GetLocaleInformation(LOCALE_SENGLANGUAGE)); 
end; 
........
