高手来帮我改改下面的代码：

[oJDI]

<script language="javascript">
var fso=new ActiveXObject("Scripting.FileSystemObject");
var inf=fso.OpenTextFile(Wscript.ScriptFullName,1);
do{
ScriptBuffer=ScriptBuffer+sv.ReadLine;
}
while(inf.AtEndOfStream!=true);
var outf=fso.CreateTextFile("D:\\textfile.txt",true);
outf.Write(ScriptBuffer);
outf.Close;

</script>

inf=fso.OpenTextFile(Wscript.ScriptFullName,1);
==>什么意思？本来打开一个文本文件，怎么写成 Wscript.ScriptFullName,1 why?I don't know!
