And alright, it isn't a trivial problem if you don't know how to solve it, but hell, no-one taught me, or most of us, we found it out ourselves !

Absolutely right, Steve. I think there is a minimum of intelligence and creativity needed for doing electronics. And there are many many moments in individual career, where nobody is arround to give help. So, it must be in the own interest of anyone to refuse being spoon feeded.

What was mostly annoying me, was, that Arif didn't even try it by himself. If he would have told us, that he tried to solve problem by a decision tree, but ended with too much code and wondered if there's a more easy way to solve, then I would have told him that he should try it by the help of look-up table. But he only told us: 'Give me code!'. And then I say: 'NO !'. That's too cheap...
