Think of the tag in Label as a line number - for instance, Label[L100]. You can then use Goto[L100] to move control to that point. The help shows (in v5.1) shows all the commands on one line - you can put in line breaks after each semicolon command break (;) to help make the code more readable. BUT - before you go ahead, a recommendation: Don't use Goto!! It's a horrible command that you should never need to use. It's only included in Mathematica for completeness. There are far more efficient ways of doing whatever task it is that you want, that will run faster, and that you will be able to understand when you come back in 3 months (or whatever) and try to debug or modify you code. Perhaps if you post what the problem is someone in the group could suggest a 'standard' way of doing it.
