In Delphi, how can you have currency data types shown in different currencies in different forms?

function CurrFormatFromLCID(const AValue: Currency; const LCID: Integer = LOCALE_SYSTEM_DEFAULT): string;
var
  AFormatSettings: TFormatSettings;
begin
  GetLocaleFormatSettings(LCID, AFormatSettings);
  Result := CurrToStrF(AValue, ffCurrency, AFormatSettings.CurrencyDecimals, AFormatSettings);
end;

function USCurrFormat(const AValue: Currency): string;
begin
  Result := CurrFormatFromLCID(AValue, 1033); //1033 = US_LCID
end;

function FrenchCurrFormat(const AValue: Currency): string;
begin
  Result := CurrFormatFromLCID(AValue, 1036); //1036 = French_LCID
end;

procedure TestIt;
var
  val: Currency;
begin
  val:=1234.56;
  ShowMessage('US: ' + USCurrFormat(val));
  ShowMessage('FR: ' + FrenchCurrFormat(val));
  ShowMessage('GB: ' + CurrFormatFromLCID(val, 2057)); // 2057 = GB_LCID
  ShowMessage('def: ' + CurrFormatFromLCID(val));
end;
