Two things: First, you obviously haven't tested this with actual code, otherwise you would have noticed something. Secondly, you can't get an infinite loop without actually having a loop there. You have an assignment followed by a forward branching if, no loop. ---- Geoff --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
