Internals pkg and source code - When first starting Newton development I fiddled around with some basic principles, like lists. ProtoTextLists seemed pretty interesting, but the sample was a little too simple. So I extended this code a little, cleaned it up and discovered/learned a lot during this work. I must say though that I wrote this a month ago, did some major Newton development after that, relooked at the code again yesterday, and cut at least one third of the code and slots! I hereby give this code away for free, not because it's a great wonderful tool (far from), but because it might give other novices some help.
