Induction specifically avoids needing any end-of-file signals.You can only prove equality up to every desired step.Induction proves it for ALL n in |N.> But it can also be stated by induction that d cannot be more than all> its FISs which also are in the list.

We might all be better off merely killfiling WM's nonsense, but he makes such silly mistakes that we cannot give up the fun of finding them and pointing them out.--
