The goto's did get my nerves bristling a bit on first sight - but it's the right tool for the job (or at least gets the job done), so I was OK with it. I guess other languages may have better/cleaner ways to achieve it.

I love the discussion that it sparked here too. It's wonderful and educational to see so many smart people breaking down the problem space, discussing de/merits of this particular technique, presenting alternative approaches with analysis on memory use, performance..
