Try describing to us what you think the code does, and we'll check if you're right (or how right you are).

You'll learn more if you think it through and describe what's happening so others can understand rather than simply getting others to do the work for you.

What are all those dots?

Anyway: Bumping your thread is very impolite. Now I can't speak for all of us, but I personally haven't got a clue what you're asking. You understand the program, but you don't understand the program??

So ask a clear question about what you don't understand.

You have a SONY CD-Player and if you click the button it plays. Where is the problem???
