I can think of a couple things that you could do. 1 create an interrupt table to take care of it. . . THis is a royal pain in the ass so I don't reccomend it. BTW can you store an interrupt routine in the stack, or is that used by the system too? 2 Type your notes into y= and save em with a stor GBD or whatever, this would be the easiest and best way to do it, I think
