nyc: Sorry I wasn't clear. 8 clusters of 8-30 front panel numeric controls each. Is there a way you're talking about that wouldn't require a case for each element of the cluster?
nathand: Thanks for your input. After further thought, I agree with your analysis. I'm going to move ahead with the "best bet is an enumeration on the front panel, wired to a case structure somewhere in the backend that pulls out the right cluster element. It's a bit of work but expresses the goal clearly in the code, and allows you to limit which parameters can be changed." It will be a bit of work, but does seem to be the most transparent code and least likely to introduce bugs.
