The exhaust that in mentioned (exhaust ==LOW) is a Boolean. I tried{} but cord in not compiling.
As I said in Reply #8 I don't understand what you want that line to do and you have still not told us.
You need to tell us what is the purpose of the line and if it won't compile and you need help then you need to post the complete program and post the compiler error message.
Keep in mind that we cannot see your PC screen from here.

PS writing coherent sentences without typos would also be a big help. You need to read back your stuff after you have composed it and consider whether a stranger would understand it they way you want it understood.
