实验九，我的代码如下
大家可以参考一下 我傻了。。。。两个语句没区别。。。 应该用DEC 本帖最后由 zyk524 于 2020-10-30 22:17 编辑

正确代码如下 assume cs:code,ds:data
data segment
db 'welcome to masm!';可以用字符（我当时挨个查的ascll码）
db 0ah,0ach,71h;16开头
data ends
code segment
start: mov ax,data
mov ds,ax
mov ax,0b800h
mov es,ax
mov si,0
mov di,0
mov dx,3
s1:mov bx,0
mov cx,16
s: mov al,
mov ah,
mov es:,ax
inc bx
add di,2
loop s
add di,128
inc si
dec dx
mov cx,dx
jcxz s2
jmpshort s1
s2:mov ax,4c00H
int 21h
code ends
end start
