在编制键盘输入程序时常常要用到一个键的扫描码或ASC码，如用到 Foxpro 的 inkey() 函数，以及用到 BIOS 的 INT 16H时，但找一个编码表不太容易，有时候找到的编码表又不全，无法查到组合键的编码，本程序就是一个随时用来显示按键的ASC码及扫描码的程序，可以用 16 进制和 10 进制同时显示一个键按下和放开的扫描码，以及ASC码，同样也支持组合键。-Keyboard input in the preparation procedures are often used to a key scan code or ASC code, such as using Foxpro

汇编程序实现： 程序功能:用深度优先搜索法解决八皇后问题并打印结果. 列数行数分别用1-8标记.所以八皇后的位置申请了9个 调试感慨:汇编调试实在麻烦,不像C中在任何地方加个printf就可以知道 哪错了.跳来跳去的,不知哪里死循环了,实在不好调试. -Assembler to achieve: program features: Using depth-first search method to solve the eight queens problem and print the results. Out a few lines with 1-8 marks, respectively. Therefore, the position applied for 8 Queens 9 debugging feeling: it is troublesome to debug compilation , unlike C, plus a printf in any place can be known what is wrong. jumping around, and I do not know where the infinite loop, and it is not good debugging.
