Casio FX-880P

I'd like to share tricks and programs suitable for this excellent pocket computer by CASIO. I've discovered a lot of hidden features of this calculator. Do you want to try some new BASIC commands?

Here are some of my programs for the FX-880P.

The first is a game: The Little Castle. It uses the graphics of this calculator over their limits... you will see castles, towers, swordsmen, candles, cars, bats, treasures... you need a little bit of fantasy, this is not a 32-bit 3D Voodoo Graphics action game, but if you like FX-880P, this should be a must for you. If you enjoy this, please let me know your opinions about it. Note:…
