本程序用于双字节数转BCD码显示，由于16位数最大值为65535，最高位为万位，所以采用一种特别的转换方法，特别声明：本程序只适用于双字节数据的转换，不适于三字节以上数据的转换。-the procedures for double byte few BCD switch shows that the median maximum 16 to 65,535. The maximum spaces for 10,000 and the use of a special conversion methods, in particular statement : The procedures apply only to double byte data conversion and unfit for more than three byte data conversion.
