Continuously run program

Is there a way to make a program where you cannot exit and it continuously runs?

You can use an infinite while loop

while true do
insert code here
end

The only way to stop that will be with either ctrl+t, ctrl+r, or ctrl+s.

Well or if you tell it to break the loop by doing something like

while true do
some stuff
if input == "exit" then -- can be whatever you want just an example
  break -- will stop the while loop
end
end

If you then also pull raw events instead of sleeping or using read(), you can block the terminate key sequence. Just run that program from the startup and it'll be a bit more difficult to bypass.

Like above, you can add os.pullEvent = os.pullEventRaw to your program. Like this:

os.pullEvent = os.pullEvenRaw

while true do
insert code here
end

Just remember that by doing something like "os.pullEvent = os.pullEventRaw" you may be messing with the global os.pullEvent and this may overflow into other programs. If your going to go this route the best thing to do is to do some cleanup prior to exiting your script and restore the original os.pullEvent function(unless it doesnt matter and you do not want to use ctrl+t any where).

local os.pullEvent = os.pullEventRaw?

Have you tried that? It won't work, you can't make a variable (the pullEvent function) inside a table (the os api table) local.
