If you will be storing sensitive data to a file (high scores, progress) I highly, highly recommend using the DAT file type instead of TXT DAT stores an array of numbers, and cannot be viewed or changed in the text editor DIM D[1] D[0]=MYNUMBER SAVE "DAT:SAVEDATA",D You want to save not very often so the user is not bombarded by dialogs saying "Would you like to save blah blah blah?"
