PassLock secures your TI 89 (well, not in the screens center), TI 92+ and Voyage 200
calculator from guests trying to steal your programs, play games, and erase the memory.
(in fact, people like classmates!!)


How to use PassLock ?

Using PassLock is very simple, just send the file 'passlock.9xz' to your TI-Calc and run it.
The first time you run it, PassLock will create a file ('main\plfile.plf') in which the password
will be stored. This file will be archived, I dont recommend unarchiving it!!

- Press Enter to lock the calc

The calc switches off immediately. After pressing ON PassLock will prompt for the password.
The screen behind the password will be blanked out, so you dont have to mind clearing secrets.
After entering the password PassLock stoppes execution and the calc will be in normal state
again, showing the Home screen.


- Press Apps to change your password

Youll have to enter the active password at first, then PassLock will prompt for the new
password twice. The entries for the new password have to be equal to be updated.


- Press ESC to exit PassLock

The very first time there wont be any password stored, so if PassLock asks for a password,
press enter and itll be fine.

Hints:
- You can only use numbers and small  for the password.
- Forgot your password? If your calc isnt locked, just unarchive and delete the storage file!
  WARNING!! If you forget your password and PassLock is activated, the only way out is to
  reset the calc!

Added external file support.

v1.1
Assembly program corresponding with external BASIC program which handled the password storage
(Not good anyway, because it required KerNO)

v1.0
First version, password stored in a global variable (need to be unarchived to change the password)


Credits

Program and first beta tests by
Christian Hofstadler

Thanks to my classmates for testing my programs and giving hints for better ones,
especially Geno, Greeni and Fu.

Also thanks to the TIGCC-Team for that cool compiler (PassLock is written and compiled with
TIGCC IDE v0.94) and for that huge help-file (I wouldnt have been able to write PassLock without it)
