实验九代码，向大佬求解代码问题在哪
assume cs:code,ds:data,ss:stackdata segment
db 'welcome to masm!'
db 02h,24h,71h
data ends
stack segment
dw 8 dup (0)
stack ends
code segment
start: mov ax data
mov ds,ax
mov ax,stack
mov ss,ax
mov sp,10h
mov cx,3
s: push cx
mov cx,16
call s2
loop s
s2: mov al,ds:
mov es:,al
inc bx
inc si
mov dx,ds:
mov es:,dx
call s3
ret
s3: pop cx
inc di
mov si,0
mov bx,0
mov dx,0
ret
mov ax,4c00h
int 21h
code ends
end start
报错如下
用小甲鱼视屏里的代码执行到push cx时也会报错：instruction or directive
和53行报错：symbol no dinefind

end start 截图的报错是上面我自己代码哪里的报错

都报错到第13行了，你就不仔细看看吗···
start: mov ax data
mov ax,data
你的逗号呢
附上我的实验9代码供参考：
