Toggle output using only one program

ok, sorry if this is an awfully noob question but, how would i make it so that if i say "lights", for example, and the lights are on, they turn off, and vice versa, instead of having two separate programs. im using bundled cable output btw.

also, i have another question, how come when i use

c = colors.combine( c, colors.red)
rs.setBundledOutput("back", c )

for example, upon restarting the computer or the server i need to use the program TWICE before it outputs?

Use this! Free of charge. And don't feel bad about it being a "noob" question, it took me some time to fine tune it.

while true do
shell.run("clear")
print("Would you like to turn on these lights?")
input = read()
yes = "Yes"
no = "No"
to = "Turn off"
if input == (yes) then
print("Well alrighty!")
redstone.setOutput("back", true )
end

if input == (to) then
print("Turning off!")
redstone.setOutput("back", false )
sleep(3)
end
end

Type 'On' turn it on. Type 'Turn off' to turn off.

I just realized, this is for normal redstone, not bundled. Oops. But you can still use this, just edit it to your needs.

ok, that helps, but can someone please answer my second question? its really annoying every time the server stops, that i have to type things into the console twice for them to work, is there something other then the color api i can use to set bundled cable outputs to false specifically? or am i doing something wrong.

I have no clue, I'm sorry. But as long as your happy using just normal redstone or red alloy cable, then you should be able to use my program.

Try putting this at the top of your code to eliminate the need for the 2nd.

c = colors.combine( c )

Not sure why its needed, but seems to work.

It should be c = rs.getBundledOutput(side)

Then the combine should work first time - if it doesn't it is something in your code.
