Hi Ken, thanks for your reply ! :)
...sorry, I forgot to mention a certain aspect: The list begins with unwanted items and after that, all following items are wanted. Finding the first wanted item means: The search is over now, from here happiness will start! :) "Filter"ing means to crawl down the _whole_ list, inspecting each and every item of the list while assuming that wanted and unwanted items are well mixed like tutti frutti. sorry for not getting the specification right... ;) Cheers Meino Ken MacKenzie <deviloc...@gmail.com> [16-11-01 18:47]: > I am wondering why not use a filter on the list? > > Ken > > > On Monday, October 31, 2016 at 10:53:25 PM UTC-4, meino.cramer wrote: > > Hi, > > > > I have a loooong list of something.
