variables

[HereWeGo]

Very basic question, but can you pass a numerical value from a main vi to a subvi using a global variable or do I have to use the call by reference node?  I seem to get errors when to passing an integer to the void global variable.

Hi HereWeGo,

what do you mean with a void global variable? Your global has to have the same type as the data you want to write to it. If you use a "normal" subvi call, than use a control in your subvi, and connect the value directly to it. Can you explain what you need? Run your vi´s in parallel?

What I am trying to do is take the channel name and attach {delimiter} after each channel name except for the last channel name.  Would a case structure be the best way to go.  My code is attached

This is one way. I don't quite understand the use of your {delimiter}. That's just text and not an actual delimiter.
