Thread: Would this be considered defining a funcion?

I'd like to run a block of code interspersed throughout a program and rather than making a mess in the program I'd like to define it as a variable. I'm not sure if that's the right terminology but I'd like to represent

Code:

  // read the state of the Relay value:
  buttonState = digitalRead(buttonPin);

  // check if the Relay is on.
  // if it is, the buttonState is HIGH:
if (buttonState != HIGH) 
{ 
break;
}    
    // exit program

with a single word/variable etc. Is that possible? It'd make my program much cleaner and easier to follow if I don't have to tack this mess in everywhere I need it.

thanks in advance for any advice!!

Is there no way to define an entire block of code as a command?

Sorry if this is a dumb question. I'm new to C.

Once again I'd like to condense a group of code into a single function. I'm a newby and unfamiliar with how to do this.

So have you read the tutorials on this site about functions? Have you looked at any of the threads about functions on this message board? What's stopping you from doing so?

See... no problem.

That's quite a welcome! Thank you. Wow.

As far as reading, I've done some (Ritchie's book and a few others). I will have to do more. I am learning C and am in a rush on a quick project. I figured this would be the place to get zeroed in on a specific area to research just what I need. I have a lot of irons in the fire with a business I'm trying to maintain right now and haven't had tons of time to learn C other than the bare essentials.
