How to find or create the iteration number box in a For loop

Question

I have a large, somewhat messy For loop in which I can not find the iteration number box. Is there any way of searching for this component or simply creating a second iteration number box?

Answer 1

You can't create a second iterator terminal, but you can use scripting to move the iterator to a typical location (bottom left) with this VI Snippet.

Be sure the file is open before running the script.

Answer 2

This is a bit of a gamble, but you can try the Clean Up Diagram tool and see if that helps. If it doesn't it should still expose the iteration icon, and you can find out what wires it is connected to. Hit Ctrl-Z to undo the clean-up, and double click on the wire indicated previously and it should expose everywhere the wire routes to. Hopefully you can track it down then.

A messy diagram means that sub-vis or an architecture re-design is badly needed.

Answer 3

Depending on what version of labview you are using, you can use Block Diagram Cleanup tool, as mentioned by Austin. But you can also highlight a section of code and clean that up individually. This 'selective cleanup' feature was introduced in 2012.

Regardless, you can't search for an iteration counter. Use your eyeballs...how bad could this for loop be? Hint hint: I want to see it :-)
