Probes for Loop Iteration

[Vinny_Burzi]

I would like the ability to probe the loop iteration terminal ("i" in For and While Loops) without the need to wire it to something (indicator, edge of structure,...).

The i terminal is the most common use case for this, but this will probably be useful on any unwired output.

The main problem I see with this is that it has some performance implications. Currently, if LabVIEW sees code which has all its outputs unused, it ignores it when compiling the VI. I would say that if this takes too much effort, special code should be written to support just the i terminal as early as possible.

If there are performance issues, it could be off by default and only available if we enable "deep probing" or similar. It could be part of the "retain wire values" option.

LOL, If I remember right, this feature request was mentioned on a wish list on infoLabVIEW (or similar) sometime in the last century. 😄

I can't count how many times I've wanted this myself.  This would be great.

Great suggestion. I frequently need to see the value of the loop "i" terminal.

Great suggestion !

the way I currently do this is to wire the i terminal to the bottom of the loop

EDIT:  Sorry I just read your post more closely and this is what you already do

You should be able to do relatively easily using a combination of the JKISoft RCF ( http://jkisoft.com/right-click-framework/ ) and the JKISoft WireNuts ( http://blog.jkisoft.com/news/announcing-the-new-jki-wire-nut-toolkit-for-labview/ ).

Great idea!

The biggest need for this is at run time, when you cannot wire.

totally agree. kudos
