（汇编程序）使用MASM 5.0工具，完成10字节长两个压缩无符号BCD数相加的实验程序。两个操作数最好从键盘输入，采用数据段定义（常数）也可以。调试通过、运算结果正确、结果可观察，程序运行具有容 错性、代码编写风范良好、语句行适当注释。-(Assembler) using MASM 5.0 tools to complete the 10 bytes long compressed unsigned BCD number two added to the experimental procedure. The best of two operands from the keyboard input, using the data segment defined (constant) is possible. Debugging through the computational results are correct, the results can be observed, the program runs with fault tolerance, good coding style, the statement line appropriate comments.
