ASP编程中最头疼的就是调试程序的时候不方便，我想可能很多朋友都会用这样的技术“response.write ”，然后输出相关的语句来看看是否正确。前几天写了一个千行的页面，里面大概有七八个SUB/FUNCTION，调试的时候用了有三十几个 response.write ，天，调试完后把这三十个一个个删除，累！

　　今天看到一个ASP编程中的Debug类（VBS），试用了一下，绝！

　　使用技术很简单：

　　test.ASP编程

<%
output="XXXX"
Set debugstr = New debuggingConsole
　　 debugstr.Enabled = true
　　 debugstr.Print "参数output的值", output
　　 ''……
　　 debugstr.draw
Set debugstr = Nothing
%>
