汇编程序：按键按钮，查看绘画

Question

当按下't'键时，我的程序应该从显示开到闭眼。有坐标。

我尝试用

做到这一点

mov ah,01   ;waiting for the button
int 16h
cmp al, 116 ;compares if t char is pressed

但它不起作用。

我的代码：

.model  tiny
.code
org 100h
start:

mov ax, 0003h       
int 10h


jmp ekranas

ivestis:

mov ah,01   ;waits for button
int 16h
cmp al, 116     ;compares if t is pressed

Answer 1

你正在跳过你的关键例程：

jmp ekranas

此外：

mov ah,01;waits for button

应该是：

mov ah,0

值为1 =获取键盘状态，0 =等待按键。
