Jeeze ... I suck as this apparently than. So I've done part of it right, I think. I downloaded the file, saved it, and move it to MyLib. I saved the file as autofoil. However when I enter autofoil\foil my calc says "library document not found". Also I was asking earlier is their a way to find library documents without entering autofoil/foil all of the time. Having to type it in than search for the "\" key is kinda annoying. I was hoping their was an easier way to find the program in the calculator.
