    For instance, ¬ b means "no b", in some logic texts (IIRC Principia Mathematica by Russell and Whitehead uses it). That is, it'll be the same as !b.

                Actually I don't believe it does. That's not Greek ;). (I have actually written APL and it's great, once you get your head around it :P.)

                              Dad always thought laughter was the best medicine, which I guess is why several of us died of tuberculosis. I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world, because they'd never expect it.

                                      It is great, but the keyboard takes some getting used to.
