I checked the IDL manual, and also compared the code with codes I saw on different websites, but could not find out what's wrong with the syntax of the case statements. So I guess something subtle is going on here, and it's quite frustrating, because I tried different things, and also some different examples, but they all gave this kind of syntax errors. So there must be something that I have done totally wrong.
