After a couple of days searching i didn't know that i should have look for a syntax like you mentioned
I was searching the wrong direction
Thank you also for the extra tips
So i have a lot of homework now
Must I close this question in some way, or do i have to do something else to keep things surveyable ?
No, you don't need to do anything to close a question (although a feature allowed people to mark questions as resolved has been suggested in the PerlMonks Discussion section in the past).
