start:mov ax,a
mov es,ax
mov ax,c
mov ds,ax
mov bx,0
mov cx,8
s1:mov ax,es:[bx]
add [bx],ax
add bx,2
loop s1
mov ax,b
mov es,ax
mov bx,0
mov cx,8
s2:mov ax,es:[bx]
add [bx],ax
add bx,2
loop s2
mov ax,4c00h
int 21h

end start
这里面的的下划线的语句里的ax应该换成al？定义的是字节型数据啊！
------解决方案--------------------------------------------------------
s1:mov ax,word ptr es:[bx]
加上大小
