Thank you for your answer! Figuring what to do is not always easy, but I will most certainly follow your tip about "How do I do X".
But regarding logging, is this a file called log, or are there programs where you write the log?

Logging is a big topic and there are as many ways to do it as there are programmers. Some people like to log a lot of stuff (for example, every time you enter and exit a function, some people will write an entry to the log! That way they can see how the program is running. Personally, I hate that :-) ). Some people like to write only error to the log.
