16位汇编 call调用函数 通过栈来传递参数

计算N的3次方，N做为参数放在栈上

assume cs:code, ds:data  
  
data segment  
    dw 0
data ends  
  
code segment  
      
    start:  
      
    mov ax,data
    mov ds,ax
    
    mov word ptr ds:[0],2
    push word ptr ds:[0]
    call cube

    mov ax,4c00h  
    int 21h  

    cube:
     mov ax,word ptr ds:[0]
     mov bx,ax
     mul bx
     mul bx
     ret    
      
code ends  
  
end start  
  
end
