      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.)

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