Question

我修复了我的程序，但现在循环似乎被卡住了。每当我按 u 或 d 时，它就会卡住，但鼠标部分可以工作:)

有关解决此问题的任何提示吗？我尝试了很多东西，但它似乎没有用。我会尝试更多的东西，但任何建议都表示赞赏。

Answer 1

您在寻找这种中断服务吗？ INT16/AH=01h

你可以这样使用

mov ah, 01h
int 16h
jz _no_keyboard_input_present
jnz _keyboard_input_present

Answer 2

感谢您的建议knm241。上面的程序现在可以正常工作，谢谢你。发生的唯一问题是键盘缓冲区没有清除，因此程序会陷入循环。我通过清除缓冲区来修复它，现在一切正常。

我用这个宏来清除缓冲区。

并将其添加到FASTER和SLOWER之前跳回到循环中。
