Also, another solution to your problem.
If you don't want your teachers to delete all your programs, and you have an older version of the calculator. Download HULL from the file sharing section of this website( http://www.casiocalc...S.FX.9860G.casm and scroll down to the program called "HULL")
It is a program that displays a fake version of the calculator OS, and when the teacher goes to delete your programs, nothing will be deleted in the actual OS.
HULL only works if your calculator is the old version (with SH3 CPU), an easy way to check is if you check your OS version in System, the SH3 calculators will end with a 0 and the SH4 calculators will end with a 1.
If it's SH4, you can download my program instead which is called FakeOS, it works on SH4 calculators, but it is not as complete as HULL. https://github.com/V...mi/Casio-FakeOS
