Hi, but using sed is compulsory.

Then your example was misleading me. Any time I see complexity like you describe, it makes me wonder about the analysis performed. Should be looked at. But when we get fractional part of it, we end up playing 20 questions (if you know the game) and not really helping you. So I'm in the way of progress here. I'll let Rudi see if he can get through to what you need and asked for - note those are not always the same.Smilie
