问题描述
这是我的汇编代码.它不工作.. 我试图用另一种方式写它，但这给了我其他错误 我使用emu8086 .....在第一页中将有3页(1,2,3)，您必须选择 页面.
this is my assembly code . it not working .. I tried to write it in another way but it gives me other mistakes I use emu8086..... in first page there will be 3 pages (1,2,3) and you have to choose which page.
1-学习2次考试3次退出
1- study 2-exam 3-exit
- 研究:将从0-9开始学习乘法表
- 考试:有关0-9岁多人的问题
- 从测验中退出
，完成测验后将出现标记.
and after finish quiz there will be mark.

推荐答案
错误列表:
nl db ,10,13,"$"
多余的逗号表示多余的零.您得到的是db 0,10,13,"$"
The extra comma translates to an extra zero. What you get is db 0,10,13,"$"
mov ax, data
mov dx, ax
要设置段寄存器，您需要编写:
To setup the segment registers you need to write:
mov ax, @data
mov ds, ax ; Do read carefully: DS
mov ah,7
int 21h
cmp al,3
je t1
当用户按下标有"3"的键时，您将在AL中收到代码51.
因此，您的支票应该为cmp al, 51或更好的cmp al, '3'.
When the user presses the key labeled "3", you will receive the code 51 in AL.
Your check therefore should be cmp al, 51 or better cmp al, '3'.
t1: mov ax,3 <<<<<< This sets AH=0
int 21h
lea dx,std1
int 21h
mov ah,7
int 21h
由于AH=0是ProgramExit函数，因此后续代码均不会执行.
Since AH=0 is a ProgramExit function, none of the code that follows will get executed.
mov ah,7
int 21h
您的程序包含很多这样的内容，并且您不会使用AL中的结果.如果这些是您的调试工作，则应该在此论坛上之前将其删除.现在，这对于任何阅读您的程序的人来说都是很困惑的.
Your program contains lots of these and you don't use the result from AL. If these are your debugging efforts, you should have removed them before posting on this forum. Now this is very confusing for anyone who reads your program.
