Joe,

Right, and thanks for the reply. I actually have a Treeview Control that's populated by a recursive program, much more along the lines of correctly answering my own question. I'll be posting it here this week as soon as I get a minute.

Best,

DD

This is what happens when you ask the question "Where can I use recursion?" What should happen is "I have this requirement, now what is the best way to satisfy this requirement?" If the answer is recursion, then go for it. But I think it makes sense to wait for these things to present themselves rather than trying to dream up situation where recursion can be used.

This works because of the way the English language deals with numbers (235 = "two hundred and thirty-five", 235000 = "two hundred and thirty-five thousand", etc.). You have the same basic function and just add a decriptive to the group of numbers (thousand, million, billion, etc.). BTW, I don't think we've ever written a billion dollar cheque. I also don't know if this would work for other languages too. I know a lot more computer languages than human languages.
