Offer a Positive Logic Alternative

[JackDunaway]

As we look at the Comparison Palette, there are three functions that offer negative logic, but fail to offer the positive logic alternative:

I commonly find myself placing a Boolean "not" right after these functions (e.g., if I want to know if there are elements in an array I must test if it is "not not empty", or if I want to know if a ref is valid I must test if it is "not not valid". Take a look at my other idea which illustrates not not logic.).

I have two proposed solutions: 1. offer a single function that has an "Invert?" option on the output, or 2. offer both the positive and negative logic primitives on the palette.

It's a good idea.  If I had a choice, I'd go for inverting the output (with a little circle on it to show it's inverted).  In fact, I'd like to see that on almost everything in the Boolean palette...

[JackDunaway]

I agree with crelf about wanting the "Invert?" option on every output on this palette.

Moderator: Ravens is right. Would you update my original post with the correct link? Thanks!

And kudos for the idea

The link provided by Ravens Fan links to this idea.  I looked briefly through JackDunaway's ideas but I'm not sure what the link should go to.  Can someone provide an updated link?

Laura: This should be the correct link: http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Allow-References-to-be-Wired-into-Case-Selectors/idi-p... Thank you, Jack

Dohh!  I got mixed up between windows when I was trying to copy the correct link so I could paste it in the message.  Yes.  Jack's new link is the correct one.

I'm sorry about that, everyone.

Back to the Idea... Yes, yes, yes.  I would also like the option to invert inputs individually (and outputs) to the booleans as is done on the compound boolean.
