Number will not leave "For loop"

[ghuffines]

On the right side of my block diagram, the "0" or "1" that I am trying to get to leave the for loop to go to the case structure below it will not leave when I use the highlight exicution function I see the data stop at the border of the loop.  I need the loop for timing.

The data can't be seen by anything "after" the For loop until the loop ends. You have to think about it like a flow chart.

LabVIEW programming is based entirely on dataflow and parallelism. This is incredibly powerful and has lead to its success over the years (coupled with the graphical programming), but is usually one of the first things that new developers stumble over. Here's a simple resource to become more familiar with how it works. The Highlight Execution feature is a great way to watch how your application utilizes dataflow and you're seeing correctly how it won't leave the loop.

To show the current value within the loop, you have to move the indicator inside. If you want an array of all values that are being passed out of the For loop, right-click the tunnel on the edge of loop and select "auto-indexing". This will give you an array of all the values that you can display using an array of integers indicator.

James hit everything very well. I'd also add that the dynamic data hides (or confuses) what you are actually looking at. I'd rather see a green wire for boolean, than some mystery blue wire. You can try the "In Range and Coerce" function instead of that express VI.
