Note : Since the Integer type in Visual Basic is signed integer. Its range is within -32768 and 32767. In Visual Basic, if you want to set c0 or c2 as value larger than 32767, please set it as the intended value minus 65536. For example, if you want to set c0 as 40000, please set c0 as 40000-65536=-25536.
