Welcome to the TI-Basic Developer! I've said it once and I'll say it again, it's great to see people joining the TI|BD community through word of mouth!
I checked out your program, and its capacity is technically good — just beware of the "all in one" trap, where too much in one program just confuses the end user. But otherwise, I'd say that it works pretty well.
And you are right, that documentation is pretty darn good. It's always good to spend time reading quality documentation. You did make me laugh, when you made your program do something and you don't know what it is exactly, but remain convinced that it's probably useful =D
Be sure to fix the typo in your next version. In your READ ME FIRST.txt, you spell guarantee incorrectly, and in one of your notes of the document, you say "computer" rather than "compute".
I am certainly looking forward to more programs from you.
