how to protect a textutils.slowPrint against termination

Is it possible to protect this against termination? I've tried using pcall a few ways and they didnt work.

textutils.slowPrint ("::::::::",5)

If you put this at the start of you program:

local oldPullEvent = os.pullEvent
os.pullEvent = os.pullEventRaw

And this at the end:

os.pullEvent = oldPullEvent

It won't throw a terminate error. However, ctrl+s and ctrl+r will still work. There's no way to prevent this, except by putting your program in the startup file, so that the program will run when the computer is started up again.

I already knew that as computers shutdown when the server restarts so i was going to have to do that anyways, but thanks for the os.Pull event stuff

or just pcall() it :)/>/>

I tried pcall()ing it but i must have been doing it wrong
