HP Prime: password protection for programs

[Davi Ribeiro de Oliveira]

Hello friends:

Every day we are more familiar with the Prime HP. I wonder: is there a program that protects accidentally deleted a program be? Something like putting a password to access the program? Installed a program called "KEYY" more do not know how to use it and not for that exactly fits.

Can anyone help?

Thank You

In a similar vein, I sometimes mistakenly get to the program editor and inadvertently hit a key that makes a change in the program itself, so that I get a error when the program is checked for errors. Sometimes I do not notice the change, and the program will not run when when hitting the RUN key and I am scratching my head as to why the program will not run when it did a few minutes earlier.
It would be nice to put a properly running program in a state where it could temporally not be modified by selecting a switch.
The switch could be turned off if additions or modifications really need to be made.

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!
