stack segment stack
dw 100 dup (?)
stack ends
data segment
x1 db 'please input a letter','$' ;必须'$'结尾
x2 db 'zhongyunde','$' ;
data ends
code segment
assume cs:code,ds:data,ss:stack
start:
mov ax,data
mov ds,ax
mov ah,1h
int 21h
cmp al,0
jz start
call far ptr xx2
code ends
xx2 proc far
push ds
xor ax,ax
push ax
mov ax,data
mov ds,ax
mov dx,offset x2
mov ah, 9h
int 21h
ret
xx2 endp
end start
下面是出错提示
data emitted with no segment??
不知为什么有问题?

jz start
call far ptr xx2
code ends
对主段缺少返回
应该是:
jz start
call far ptr xx2
mov ah,1h
int 21h
ret
code ends

谢谢大家的帮助
