I think we are at cross purposes on the definition of variable here. Variables come in (at least) two distinct kinds : the 3GL kind, which is basically a name for an updateable bit of store, or the mathematical/propositional logic place holder kind. So far, I've been going on the basis that relvars are of the 3GL kind. Is this merely a Tutorial D-ism ?

I don't think there is any "paradow", or even paradox (which I assume you meant) here. Only a difference in definition. Received on Wed Jun 21 2006 - 12:12:32 CEST
