利用栈，将一段数据逆序存放
assume cs:codesg
codesg segment
dw 0123h,0456h,0789h,0abch,0defh,0fedh,0cbah,0987h
dw 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0
start:
mov ax,cs
mov ss,ax;段寄存器不能互相传值
mov sp,30h//sp为30h
mov cx,8
mov bx,0
s: push cs:[bx]
add bx,2
loop s
mov bx,0
mov cx,8
s0: pop cs:[bx]
add bx,2
loop s0
mov ax,4c00h
int 21h
codesg ends
end start
