Preserving highscores from accidental opening of program code

[Kevin Ouellet]

Is there a way to make a program save a number into an external variable or memory without it being erased everytime the user opens the program code? This is problematic because all other calculator models use ENTER to execute programs, while the HP Prime uses F6, so if I have a game where the highscore is saved, then the player will usually press ENTER by reflex to launch the game, only to have not only the code opened instead but also his highscore erased.

I was also thinking of working on a role-playing game with saving options, but have been reluctant about starting such project at all because of the save data being erased over and over.
