Alright, the first beta is out!  Probably some bugs that I couldn't find, but it should be mostly workable ^^ Try it out!  I provided some instruction on how to program, but more complete tutorials like the one i posted in the original post are probably much better.

Ah yes It does look like I incorrectly named the last 3 addressing modes, the descriptions are correct though, they refer to the B argument.

Yep, I have too.

Alright I signed the app, fixed some issues with the Readme, and re-uploaded to the first post!  I also cross-posted to Cemetech; time to get people learning Redcode so we can have a multi-community battle!

I Don't plan on  adding either of those first two things, but what is a for/rof?

Lol I've said it before and I'll say it again, there is no need for real time program sending, because the users don't write programs in real time.  You could just as easily send your program to a friend and run it on their calculator

I could, but I will work on putting more useful things in the limited app space

This looks quite interesting. But quite complicated looking at it though. But I'm sure if someone puts his mind to it, he can accomplish anything(I know, it's a silly quote).
