** Setup **
Send the file lock83.83p (or lock83.8xp for the 83+).
From the shell you are using, select the program "Lock 83 v1.1".
** Using Lock 83 **
When you first run the program it will load to the main menu.
It will continue to do so until you set a password.
Press [1] to leave the program or press [2] to set/change the password.
If the password is blank, you will not be prompted to enter the old password.
If you have set a password and you set it back to blank,
the program will continue to load to the main menu again until you set a new password.
** Entering Passwords **
Any key can be pressed on the calculator for a password,
except for the [ON] button, [DEL] and [ENTER].
The [DEL] button is used for backspace.
If you enter enough characters to move to the next line,
you can't backspace up a line (you'll see what I mean when you use the program).
Press [ENTER] when you have finished entering the password.
** Disclaimer **
If you forget your password and the calculator has been turned off through the program,
there is nothing you can do. I take no responsibility for your forgetfulness!
