汇编语言：编写code段中的代码,用push指令将a段中的前8个字型数据,逆序存储b段中

assume cs:code
a segment
  dw 1,2,3,4,5,6,7,8,9,0ah,0bh,0ch,0dh,0eh,0fh,0ffh
a ends
b segment
  dw 0,0,0,0,0,0,0,0
b ends
code segment
start: mov ax,b
      mov ss,ax
      mov sp,16

      mov ax,a
      mov ds,ax
      mov bx,0

      mov cx,8
      s:push [bx]
      add bx,2
      loop s
code ends
end start
