Re: Run something only once in a while loop?

So if I understand correctly you want some piece of code inside a while loop to run only the first time the loop runs?

This can be accomplished by placing the desired code inside a case structure that is fed by a comparison with the out put of the little blue "i" block in the corner. This block keeps track of the number of loop iterations. I can't recall off hand whether it starts at 0 or 1 (I think 1) but you should be able to trigger your case structure by doing an "equal to" on the output of.

Let me know whether that made any sense or not
