下面是将定义的数据逆序，不但出现警告，而且还没有实现逆序，哥哥帮帮我

assume cs:code

code segment

dw 123h, 234h, 345h, 456h, 567h, 678h, 789h, 89h
dw 0, 0, 0, 0, 0, 0, 0, 0

start: mov ax, cs
mov ss, ax
mov sp, 32

mov bx, 0
mov cx, 8
s1: push, cs:[bx]
add bx, 2
loop s1

mov bx, 0
mov cx, 8
s2: pop cs:[bx]
add bx, 2
loop s2

mov ax, 4c00h
int 21h

code ends

end start
