So I wanna start programming on my TI-89....

[xxacefirexx]

I know a few programming languages, and even programmed a little on the TI-83

However, im unfamiliar with the syntax on the 89.

* the main reason im here is to learn how to program simple functions. here is one that i want to program first:

percentdiff(x,y)

basically i want it to spit out the percent difference of two values. i know if i see the code for this i can make countless other similar programs.

* also, are their any good online tutorials for programming on the 89?

thanks for the help!
