Hi there, newbie here,
I was thinking of creating a 3d graphing suite for the ti-83+ series.

I seem to have figured out most of what is going to be needed, but I can't seem to find a string to expression parser for axe. I figured that the expr() command could be used, but it doesn't exist in the command list.

Can I please be steered in the right direction?
Thanks!
