初学汇编,大家帮忙看看代码

代码如下:

pb55 equ 219h
p55ct1 equ 21bh

(以上代码是在图书馆的书上抄下来,代码有的地方看不明白.希望大家能帮着写一下注释 push pop segment mov jmp 这些能看懂)
谢谢大家的帮助

代码有问题，

[ccunion]

代码有问题 是不是抄错了

代玛我改了，确实有很多问题。

就能听见声音和一堆乱码，
不知道改得对不对。

To xia renjie
push pop mov 这些能看懂 程序的整体作用不是太明白 所以想请大家帮着注释一下

[xia renjie]

我感觉你书都没看，要不然怎么会连push pop 这些指令都不知道！

楼上的楼上，你的原码太乱了，搞得我的ＤＥＢＵＧ都进行不下去了．
我建议先学点短小的程序，在学这么长的程序．
