Thank you Loops! I read your post and then understood that in the second assignment I didn't just assign a rw property but that it was a complete new assignment. I finally found a way to merge both assignments, but I don't yet know whether they are correct. Then I returned to the monks page and read your update. Didn't know that the rw attribute can be set so easily :)

Now I am reading your sample and understanding much more... You are showing me the "Perl way" :) Thank you so much!
