Calling VBScript Functions directly from external program

I would like to call a VBScript function within a .vbs file directly from an external program without having to execute the whole program. I will also need to pass a couple of parameters to the function. Does anybody know how to do this? Thanks

I understand the arguments piece but am wondering how make make the call to the specific function? Or do I just use arg(0) as the function name and arg(1) as the parameter to pass to the function (or something similar)?
