Dizzy, this program!

Recently, ASP is being used as a website management system. Because of the heavy workload of one person, I am facing the computer all day long and sometimes feel dizzy. When I first dizzy, I was afraid of errors. I was afraid that I could accidentally lose a letter or miss it, so I had a CPU usage of 100%. When I look back and check the code, it's really big, it's hard to find too many letters, it's time-consuming.
A few days ago, I was dizzy. I made a program myself and checked it for a long time. I always failed to run it, prompting "invalid end character !". I was so depressed that I couldn't delete the "end" sentence and lost it again. Hey, the result is normal. Sorry, I returned to the original status again. I checked the code carefully and confirmed that it was the same as the new input program. Then I ran it, but it was a failure and I was speechless!
If you have no time, you have to wait until you have time!
