RE: LOGO-L> Word Sculpturing

[RAY CATZEL <learn@computerpals.on.ca>]

 Recursion is wonderful,
great, powerful, elegant and a real show stopper. Plus you can dazzle
your friends and co-workers. (I keep hearing the genie from Aladdin
speaking these lines). But it ain't easy (at least at first). It's a
very different way to think about problems and their solutions.  You may
want to check out one of the many books mentioned here for a more
detailed explanation and for some examples and problems to work out. 

I hope this helps and didn't make the waters muddier, regards.

[RAY CATZEL]  Thanks Frank, you are a great teacher. Your enthusiasm for the subject forced me to work through the complex logic. I think I do understand it. It is certainly not intuitive - it requires a clear understanding of how recursion uses stacks. 
One thing I have decided: it is not for younger kids. I try to push my students (all < 14 years old) as far as possible, but I think I might find it difficult to engage them in stack operation. Mind you, I have a couple of really smart kids who this might appeal to. So maybe I'll play it by ear.........
Thank you once again for a great explanation of recursion and stack operation.
