求救，我在是汇编初学者，在网上搜了一个贪吃蛇的代码，但是并不理解这些代码段的意思，有人能帮忙解释一下么？

代码功能归根结底不是别人帮自己看或讲解或注释出来的；而是被自己静下心来花足够长的时间和精力亲自动手单步或设断点或对执行到某步获得的中间结果显示或写到日志文件中一步一步分析出来的。 提醒：再牛×的老师也无法代替学生自己领悟和上厕所！ 在DosBox中使用Turbo Debugger调试。 这个里面有Turbo Debugger http://download.csdn.net/source/2805028

[大熊猫侯佩]

建议按函数分块看代码。 注意int调用，跟着调用走

[K_9527]

没有注释分析别人代码是很麻烦的，建议去网上搜一些注释比较清楚代码方便分析理解。

[把分全给哥]

同求，看不懂，但是人家的界面做的很不错，而且中断做的也很好

版主有找到这份代码的注释版吗？求发一份，我看这个看得好迷啊！邮箱[e-mail]
