Is it possible to have code running in the backround?

-----------------------------------

I need a loop to continuously be running in the background, while the program plays. Is that possible?

look it up in the turing walkthrough about procedures

RE:Is it possible to have code running in the backround?

-----------------------------------

I read the tutorial, but I am a bit confused. 

My program uses parallelput to give output to LEDs in order to resemble a traffic intersection. 

However, I need to add a crossing light, and a switch. 

When parallelget(64) = 1, then I put that into a variable: 
loop
    switchpressed := parallelget
    if ((switchpressed div 128) mod 2) = 1 then
        switchstandby = true
    end if
end loop

However, the program just continues this loop, which i want running in the backround, and ignores the rest of the code (which parralelputs the LEDs (also a loop) )

procedure buttonpressed
    switchpressed := parallelget
    if ((switchpressed div 128) mod 2) = 1 then
        switchstandby := true
    end if
end buttonpressed


loop
    buttonpressed
    parallelput (33)
    cancross := false
    delay (5000)
    buttonpressed
    parallelput (9)
    cancross := false
    delay (2000)
    buttonpressed
    if switchstandby = true then
        parallelput (82)
    else
        parallelput (18)
    end if
    cancross := true
    delay (5000)
    buttonpressed
    parallelput (6)
    cancross := false
    delay (2000)
end loop

This is my revised code. . . however, the LED only turns on if I hold the button, so when buttonpressed runs, it find the button to be 1 . . . I can't find a way to have button pressed run for an infinite amount of time, without disturbing the loop of the traffic lights. . .

Nvm, i got help from a friend. 

I made a process so the thing will run in the background.

Not much of "help" if it's the wrong solution.

A single frame of your loop takes 14 seconds to complete. So it all works, for the most part, correctly. Just very slowly. Take out the delays.

Just so I can learn, what does parallelput do?

what does parallelput do?
the bit-pattern encoding the integer argument sets the high/low pins on the parallel port. It requires some pretty old hardware and some cut-up cables, but it's an easy way to hooked up to electronic components such as 5v motors and LEDs.

Oh, so that's what I'm going to be using with my LED binary conversion project I guess...
