Avoiding locals and sequences

[Pollux]

I have coded a prototype user interface which uses lots of locals and flat sequences.

For increased efficiency I want to avoid all that. I think sequences can be avoided by rethinking the algorithm and writing some subvis that would have error clusters wired in the proper order to force the data flow. But I have no idea how can I avoid locals when I need to do increments on variables.

If you have any suggestions feel free to write here. :worship:

Here is a sample of my code.

Thank you

• You could bundle all of your controls and carry them around in a shift register to get rid of the local variables.
  
• Adding error in/out terminals to your subVIs will let you enforce data flow without flat sequences.
  
• you can replace the select statements that return a 1 or 0 with a Boolean To (0,1)
  
• use another state to sync the front panel indicators to the data cluster when necessary

I second jcarmody - these are all good suggestions. This UI scheme that I frequently use demonstrates in more detail how the keep the current UI state up to date without locals or polling by using events and bundling or unbundling into a cluster.

The LV Intermediate I course has a really good example of this using Queues.
