And 0-1 or 1/0 is «illegal» for precisely the opposite reason that 00 or 0/0 is – in the former case, there exists **no** number (real or otherwise) a, such that a = 0-1, whereas in the latter case, a = 00 is true for **every** number a. But what does all this have to do with a web site being hijacked ?... Henri
