I was too specific in the simplified example I provided--in general, I would also want to change properties other than "value", so I think I would still need references and property nodes. In that case, would I still need need to separately autoindex the references?
Your example raises another question for me as well, because you replaced my individually-named clusters with an array of a clusters. It appears that this was essential in order to have a single front panel control that can generate events. But if I only have an array of clusters, my clusters no longer have independent names that make them easy to keep track of in my program. I will eventually have something like 20 clusters to keep track of, and they will not all be treated identically in other parts of my program, so I think I really need the self-documenting nature of clusters. It's for this reason I kept them separate and had a "build array" outside the "for" loop. If necessary I could build a big cluster of the small clusters that could generate events, and then convert cluster-to-array for the "for" loop. Is there a better way?
Sorry about the auto-run VI. I didn't know it was that way or that there even was such an option.
I only have Labview 2009-10, so I can't post other versions.
Thanks.
