The most troublesome thing in ASP is that it is inconvenient to debug the program. I think many friends may use this method to " " and then output relevant statements to see if it is correct. A few days ago, I wrote a page of 1,000 lines, which contains about seven or eight SUB/FUNCTIONs. I used more than 30 during debugging. Oh, after debugging, I deleted these 30 one by one. I was tired!
Today I saw a Debug class (VBS) in ASP. I tried it out, it was amazing!
How to use is very simple:

Set debugstr = New debuggingConsole
= true
"Value of parameter output", output
