Tested on an TI-89 HW 2 OS 2.09.
This program seems useless to me because all it does it convert a string to pretty print, which you can do yourself straight from the home screen by just typing in the equation and letting the TI-OS automatically formatting it.
Every time I used this program, EVERY time, the calculator freezes. It displays the equation on the IO screen, and then switches back to the home screen, but then the keyboard freezes and the calculator is rendered useless.
I definitely would NOT recommend this program because it simply occupies you memory to do just another built-in function with no speed difference, and it also crashes your calc.
