编写80H号中断处理程序。中断发生时，显示0到9十个数字。。很急！！谢谢。。求全代码。

如题、谢了。

assume cs:code
code segment
start:
mov ax,cs
mov ds,ax
mov si,offset disp
mov ax,0
mov es,ax
mov di,200h
mov cx,offset disp_end-offset disp
cld
rep movsb
;
mov ax,0
mov es,ax
mov word ptr es:[80h*4],200h ；
mov word ptr es:[80h*4+2],0 ；
;
int 80h ；在此处加上此句就可以啦
mov ah,4ch
int 21h
disp:
mov ax,0b800h
mov es,ax
mov di,160*12+40*2
mov dl,30h
mov cx,10
s:
in al,40h
and al,0fh
xchg ah,al
mov al,dl
mov es:[di],ax
add di,2
inc dl
loop s
iret
disp_end:
nop
code ends
end start

－2、－5、－128。
