Better way to implement a help button?

Just out of curiosity, how come they use a wire running to the case structure, although they don't use the value from it?

Who are "they" and could you at elast give a hint about what example you are talking about? 😮

(Sometimes you wire to a structure to enforce execution order: The structure must wait until the wire carries new data, even though the actual data is not used in the structure)

I think I am referring to a program that you wrote, in order to subtract time from the timeout to maintain the interval for the timeout code. You linked to it a little bit up, and I meant to quote it in my post.

Ah, OK. Now I see it. 😉 In this particular case it is a vestigial wire. 😮

A vestigial wire is a wire that was functional in the past but was made obsolete due to other changes in the code. It can be safely deleted. 😄

Typically, these don't hurt except for diagram clutter. The LabVIEW compiler will ignore them as part of the dead code elimiation.

Ah, thank you! There is much less clutter now!

... in order to better identify such issues while programming, please support my related idea. 🙂
