Hej Stas....

this seemed to be a nice idea.....
BUT....
For this kind of loop I need again for every variable every year. But
unfortunately I don't have Variables for every year. Often only for
the year 2002 and 2007, but also 2004 and 2006...you see what I mean?
That is the biggest problem with this kind of loop. I think I have to
split the data set even if this means more manually work.

Best
Daniel
