QBasic Challenge :-)

[Moneo]

Moneo,
A lot of time around gets spent reinventing the wheel, because most of us program for the challenge of it. There are better programs out there than the ones most of us write, but we enjoy doing it ourselves, and showing off what we have done.

There's a certain amount of truth in what you say, but if you want to do it yourself, then why do you post a request for others to do it for you. If I wanted to do it myself, I would post requests for algorithms to do this subject, and pick the one I like and then code it myself.
