下面是代码 ，我只写了输出第一行的内容:
assume cs:code,ds:data
data segment
db 'welcome to masm!'
data ends
code segment
start: mov ax,code
mov cs,ax ---这里提示有错
mov ax,data
mov ds,ax
mov si,0
mov ax,b800h ---这里提示有错！
mov es,ax
mov di,0
mov cx,10h
s: mov al,ds:[si].0
mov es:[di].0,al
mov al,02h
mov es:[di].1,al
add si,2
add di,2
loop s
mov ax,4c00h
int 21h
code ends
end start
下面是编译的结果：
