"You left out, ' and perlmonks'"

Yes, but just because i can't answer for the other bros that contributed :-)

"The original code does not mention the author's name unfortunately"

I tried to figure out too who he is, with no success yet.

"...I did not want to leave anybody out..."

I know. I just didn't want to claim the merits for me. I only asked a question. And i got superior answers. Stuff for month to work through. Very nice.

Best regards, Karl
