汇编程序中的数制转换与DOS调用功能的结合，还有一个表处理程序，以下是程序实现的功能：

1.从键盘输入一个十进制数，转换为二进制显示在屏幕上；

2.输入十位BCD码，转换为4字节十六进制显示；

3.从键盘输入两个十进制数，相加后将结果显示在屏幕上；

4.从键盘键入一个4位十六进制数，转换为十进制显示在屏幕上；

5.对一个已知长度的从小到大的无符号字节数组查找关键字；用二分法实现-Compilation process several conversion and DOS system calls the combination of features, as well as treatment procedures for a table, the following is the procedure to achieve the functions of: 1. From the keyboard input of a decimal number converted to binary display on the screen　2. The importation of 10 BCD code, converted to 4-byte hexadecimal display　3. from the keyboard input of two decimal number, add up the results will be displayed on the screen　4. from the keyboard type a hexadecimal number 4, is converted to Decimal display on the screen　5. of a known length from small to large unsigned byte array to find keywords　realize with the dichotomy
