Wow, I looked at the source for VDodge, and it was really minimalistic...
That being said, I tried to do something similar about a year ago, and it was much slower and bulkier, so kudos to you!

You ported Lightbot to the calc?!
Voted for the sheer awesomeness: programming a game about programming a robot.

It means "You have lost the game." in latin.

Latin.  That is win.

:c
Do you really need to personally go through each and every pm?
Surely you could delegate a lot of the questions/requests...

Cool!
I'm going to go download this now.

Edit: Just downloaded onto my calc now!

This is a variant of Bresenham's line algorithm that radiates lines outwards (which you could use for raycasting (*cough*) and can draw points at intervals.
Arrows to move, clear to quit, plus and minus to increase/decrease interval.
I purposely added a pause so you can see how it radiates outwards.
(It needs optimization, though, and I'd really appreciate it if anybody could find a way to increase its speed)

Cool, bookmarked.
Also, are these all relevant/still work for the recent versions of Axe?

It probably should.  I've tried running a few programs on my TI-84+ Silver Edition, and they work fine.

Welcome to Omnimaga, btw!

I've been debating making a super-optimization guide for Axe. Should I?

PLEASE.  I would love to code like this - I still treat Axe sort of like TI-Basic, and I never really learned how to optimize that either, beyond the normal tricks.
(I just printed out your code - I'm going to be poring over it before I go to bed! )
