Using casio fx-CG500 as a Digital Diary ??

If you want to password protect you can try code like this**:


InputStr pword,"Enter Password"

If pword==(password) Then Goto [label]
Else Stop
IfEnd

Label [label]
ClrText
Print ...

If you do this, safeguard your calculator carefully.

Actually, you raise an interesting point. Many Casio graphing calculators going all the way back to the fx-8000G and fx-8500G do let you password protect text/program files. In fact, the file editor mode introduced on those models was intended for storing arbitrary text, not merely programs, with examples in the manual such as storing a list of phone numbers. I believe both the fx-CG50 and fx-9750GIII still give you this option if I'm not mistaken, and it may be sufficient to protect the data from casual snooping. I'm sure a determined attacker could still get it, though.
