Unless ... there's an even better way to do it someone hasn't thought of yet :) I wouldn't have expected there to be three ways to accomplish something I first thought was un-doable.

Yes to both.  I recently posted a multi-part series on word wrap routines in BASIC on my www.subethasoftware.com site. I wrote one, then someone sent in another, then someone sent in another, etc. I ended up with a chart showing which one used the less CPU time, which one used the less code space, and which one used the less variable/string memory. If you were in a 4K programming contest, CPU might be the least of your worries.

Exactly :) I mean, why do we bother learning math? It's already been solved. It's a great brane exercise and it's fun.
