譯者的話：

不知道用ASP寫代碼的朋友是不是和我有一樣的感受，ASP中最頭疼的就是調試程序的時候不方便，我想可能很多朋友都會用這樣的方法“response.write ”，然后輸出相關的語句來看看是否正確。前幾天寫了一個千行的頁面，里面大概有七八個SUB/FUNCTION，調試的時候用了有三十幾個response.write ，天，調試完后把這三十個一個個刪除，累！

今天看到一個ASP中的Debug類（VBS），試用了一下，絕！

使用方法很簡單：

test.asp

<!--#INCLUDE FILE="debuggingConsole.asp"-->
<%
output="XXXX"
Set debugstr = New debuggingConsole
    debugstr.Enabled = true
    debugstr.Print "參數output的值", output
    '……
    debugstr.draw
Set debugstr = Nothing
%>
