modifying user input in for loop

[mnanda98]

Hi RavensFan,

Yes, I do know what auto-indexing is and I had noticed that had been the case when I connected it with VISA close outside the for loop (that's why I had kept it inside in the first place). Ijust realized I can change that tunnel to "Last Value" which worked - thanks!

A better practice is to use a shift register instead of last value on your references. If you for loop for some reason executes 0 times (i.e. auto-indexing and your array is empty) your reference will go bad on the output side of your for loop. A shift register keeps this from happening.

Hi Greg,

Would I need to initalize the shift register or anything?

Thanks,

You initialize the shift register instead of having an input tunnel.
