So im making a door into a mall with cc. I am using a i/o of redstone to make it. It checks for a redstone signal on the bottom and if it is true then it turns pistons off. My question. How do i make the program wait until there is a redstone signal.

os.pullEvent("redstone") will wait for any redstone change.

Just so you know, you can do this with a "Memory Cell" in redstone logic...
Like this:

x = false
while x == false do
  input = rs.getInput("SIDE")
  if input == true then
	x = true
	while x == true do
	rs.setOutput("SIDE TO PISTON", true)
	b = rs.getInput("SAME SIDE AS INPUT")
	if b == true then -- have a seperate wire that connects to this side, as with the INPUT variable
	shell.run("programname")
	end
	end
  end
end

Thank you thats all i needed. So with that i dont even need a redstone.getInput?

No, once any redstone current is detected on ANY side, it will fire the event and return the parameters if any are specified.

os.pullEvent("redstone") only waits for any redstone signal change, so you need to keep calling it, and check the signal each time, until you get the signal you want.
