Thanks for the thread update and tip! That's a pretty handy feature and not widely known. I've mentioned it a couple times around here after having it pointed out to me by @JB on the Idea Exchange some years back. It deserves more publicity!
CAUTION! New LabVIEW adopters -- it's too late for me, but you *can* save yourself. The new subscription policy for LabVIEW puts NI's hand in your wallet for the rest of your working life. Are you sure you're *that* dedicated to LabVIEW? (Summary of my reasons in this post, part of a voluminous thread of mostly complaints starting here).
And possibly a subtle mention in the manual, since I suspect for many applications, being able to read back what the output is to then control the subsequent output handling is extremely useful. It could be a single line indicating the possibility exists, people can always go search out a how *if* they know that a how actually exists.
