我在汇编课上完成的一些作业（上机常见习题）和汇编课本上的几个例题，常用的输入输出模块，如： 把压缩存放的BCD码，转换为对应十进制数字ASCII码的程序；编写从键盘键入0至9中任一自然数x，求其立方值；内存中以BUFFER为首地址的缓冲区有10个非压缩型BCD码形式存放的十进制数，它们的值可能是0~9中的任意一个，将这些十进制数顺序显示在屏幕上等等，-I completed classes in the compilation of a number of operations (on the machine common exercises) and the compilation of textbooks on a few examples of commonly used input and output modules, such as: the compressed storage of BCD code, converted to decimal ASCII code corresponding to the procedure prepared from the keyboard type 0-9 in any natural number x, for the cubic value memory to buffer BUFFER headed Address has 10 non-compression type BCD code stored in the form of a decimal number, their value may be 0 ~ 9 any one of these decimal number sequence displayed on the screen, etc.
