Re: HP Prime: password protection for programs Message #3 Posted by Geoff Quickfall on 22 Nov 2013, 12:45 p.m., in response to message #2 by Harold A Climer
At the moment I create two versions of a program when working on it. One copy is the running program and the second copy is the program I modify. When the I am happy with the modified program I save it as running program. Some times I do this a few times per editing hour.
I too hit a key or am not on the cursor page when I inadvertently do something. Some one mentioned an 'undo' function, it would be useful!
