GBA Basic

A version of the basic programming language for the Gameboy Advance.

The help command can be prepended to any other key word to get info about features of the interpreter.  

I threw this together because I love the unix/pdp11 simulator for the GBA, but I wish it was interactive! I want to have the ability to spend countless hours keying-in little programs and debugging, like a pocket C64. Plus the DS has a version of basic, only seemed right. 
Any feedback much appreciated, very early demo. Thanks!
