in reply to Problem with while loop inside a foreach loop

I'm pretty sure that using named variables instead of $_ in THREE nested loops solves the issue. :)

Maybe you should take some looks into Damian's PBP?

    Thanks all, that does solve the issue. I thought that the population of $_ (following the evaluation of some expresion) was a one way thing. The idea that changing $_ can work its way back to another variable will take a bit more thought on my part. Rolf, I like your diplomacy in suggesting "Perl Best Practices" :) I have just ordered it from the big south American river!
