Edit Lock for the TI-85 is a program that allows you to lock your BASIC
programs so they become un-editable from the TI-85 Program Editor.  
This means that people you send your programs to will not be able to 
open your programs either.  This allows you to edit-protect your 
programs from people who may want to copy your code.  This program is
especially nice if you don't have access to a computer or a
TI-Graph Link cable to lock your programs with.

First of all, there are no adverse side affects to your programs by
edit locking them.  That is, if you follow the instructions.

Program Instructions:
After sending the TI-85 program "editlock.85p" to your calculator, 
run the program "editlock" from the home screen.

There several menus to pick from.  One option is informational, and
shows you how to lock your programs.  Another creates a variable 
(a string) called NULL.  Once you have created NULL with the edit lock
program, you need to open the program you want to lock in your program
editor.  So, exit the program by selecting "QUIT."

Open the program you want to edit lock.  Insert a new command line at 
the top of the program and import or insert the NULL variable, called 'NULL'
by pressing [2nd] and [Rcl] while in the editor.  A box-like character 
should appear in the new line you inserted.  Delete the quotations 
around it and exit the editor.  The next time the program (the one you 
are edit locking) runs the lock will take effect.

Locked programs will act, in a way, like compiled assembly programs 
(like compiled assembly programs on the TI-86).
If you attempt to edit an assembly program with the program editor on
the TI-86, you will get an 'Invalid' error, with the typical 'Goto' or
'Quit' menu selections.  The exact same thing occurs when attempting
to edit a locked BASIC TI-85 program when locked in this manner.  
This makes the process totally fool-proof.
