85 questions



I have two questions about the 85 but I guess it sort of applies to all TI
calcs. They are sort of naive so please don't flame me.

1) Is it true that when you take all the batteries out of the calculator,
you loose everything that has been programmed into the calc?

2) And if you have a whole bunch of programs in there (Zshell, games,
science progs), how do you change the batteries without loosing all that
stuff?

Thanks in advance for your help...
