Re: Edit-locking on TI85
This method works. Whenever the program is edited, the calculator gives an
ERROR: MEMORY, and whenever the user attempts to RCL the program into
another program, nothing is copied, as if the program were empty. There are
also no side effects (the program's size is not misreported, for example).

Subject: Edit-locking on TI85
I saw a method mentioned on the TI page to edit-lock a program on the
TI85 calculators. It is possible using Graph-Link on the TI82, but not
the TI85. I'm using a system called Classtalk where it would be nice to
lock the programs whereby students would not be able to edit the
programs. The method mention on the TI page is not supported by them,
but uses an invalid program image inside the progam image. Can someone
explain, comment on this method?
