Hi everyone,

I think I might have found a bug. (I'm new to the forums and everything, sorry if I put this in the wrong spot )

PLEASE READ THE FOLLOWING BEFORE TRYING TO REPLICATE THIS!
Don't perform these steps on one of your programs, make a new test program as the steps may cause loss of data.

Go to the program editor and open a BASIC program, then open the catalog help (I did it by pressing + on a command). Press ALPHA - ↑, it'll give you an error, then lots of weird stuff happens. My program got cleared except for one 'If'. And I was just trying to see if I could scroll the catalog faster

Thanks everyone!

EDIT: I didn't know the subject would appear so small, I am on TI-OS 5.1 on TI-84 CE.

Yep, this is indeed a nasty bug. I'll look into the OS and see what exactly is happening and see if I can't provide more information. Thanks for the information, and welcome to Cemetech, JustinYD88!
