Seymour Papert and the Logo language loved the recursive loop. It was, and still is, a very useful programming tool. Nice to see it here in a simple form Gav.
Phil, I also saw CH's post, but in light of recent event's / emotion / posts, chose to read it and take note, cut some slack and accept it for what it is. You clearly didn't. If everybody was restricted to posting only thread exact relevance replies, this forum (all forums) would stagnate and ferment or simply die. It is impossible to not post a tangential thought at times and I'm pretty sure your guilty of same at some point. Unfortunately it is a self -generating flaw in the internet forum structure. A bit like malware and viruses. We don't like them but we must manage it as best we can.
Oops, I should not have posted this reply here. It's on topic. Or is it? Where should I have posted it?
Should be soon.
