Dude, it's not complex to read the LabVIEW help on property nodes.

Right click on your 'm' value on the diagram, select 'create->property node', right click it and select 'change to write', and use the little hand tool to select the property 'value' on it. Then wire it to the output of your right hand block.

You could change the original array by creating a property node linked to its value and connecting it where your arrow is.

Why a property node?  Using the Value property is just like using a local variable except it is incredibly SLOWER.

That array should be an indicator since only the program is updating it.  Secondly, the count array should be stored in a shift register.  By using a shift register and the terminal of the indicator, no property node or local variable is needed.  And this is the perfect place for an In Place Element Structure.

Thanks. That's news to me. Why is that?

Using a property node still opens you up to the race condition issues as a local variable.  So it has no benefit over the local.  But the property node is a lot slower since it has to go through more hoops as well as swap to the UI thread.  Thread swapping is very expensive.

Thanks for the info.
