This is a very good program that nicely compensates for a major downside to the TI-OS. Just like ans(1) is pasted automatically with a +, -, *, / or ^, the TI-OS does not do this for the "|" character, and this program fixes the issue very nicely.
I definitely recommend this program because the program can be run, the hook can be installed, and then the program can simply be deleted so you don't need to have it on your calculator.
The program does permanently occupy about 176 bytes, but this is not too much of a trade-off. Download this program!
