我们就以asp教程来举例说明关于，如何在用户自定义函数调用时反回多的值，先来看一组代码

         <% 
         call getmynumber(aa,bb,cc) 
         response.write aa & " " & bb & "<br />" & cc 
         function getmynumber(byref aa,byref bb,byref cc) 
         aa=3 
         bb=4 
         cc =10 
         end function 
         %> 这里是利用了byref再看详细的

         sub test(byref a as integer, byval b as integer)
             a = 3
             b = 4
         end sub
         sub main()
             dim a as integer
             dim b as integer
             a = 1
             b = 2
             test a, b
             msgbox "a=" & a & ";b=" & b
         end sub
         输出结果 a=3;b=2byref作用是存址参数,通过操作参数的内存地址实现全局控制，
