在代码段中使用栈，将程序中定义的数据逆序存放

1.思路：入栈-出栈存放

assume cs:code
code 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
	mov sp,30H

	mov bx,0
	mov cx,8

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
code ends
end  start
