function HexToBin(Hexadecimal: string): string;
const
BCD: array [0..15] of string =
('0000', '0001', '0010', '0011', '0100', '0101', '0110', '0111',
'1000', '1001', '1010', '1011', '1100', '1101', '1110', '1111');
var
i: integer;
begin
for i := Length(Hexadecimal) downto 1 do
Result := BCD[StrToInt('$' + Hexadecimal[i])] + Result;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
ShowMessage(HexToBin('FFA1'));
// Returns 1111111110100001
end;
