Is there a way to 'comment' out code?

[Grub]

Frequently, I write bad code.... Its a fact of life for me.  Usually I have to try three or four iterations of a subVI  to get it to work just the way I like it.  SOmetime I wish that there was a way that I could highlight sections of code and click a button to temporarily disable it, while I work on other sections of code.  Is there a simple way to do this?  (apart from working on a copy, putting it in a case structure, so on...)  All I want is to be able to drag and click and have it commented....

The only way I do it is to wrap the code I don't want executed into a case structure that is set to false.  If you want to remove the "comment", make sure your original code is shown before removing the case structure.

As tuned99 said.

Use a Case Statement.  You can also wire a switch instead of a fixed boolean.  The switch can be called "ByPass ThisCode".

It is the LV way to comment out code.  The Case Statement then becomes your friend 😉

Actually, you can eventually use the "newly" created Case Statement to turn that portion of code to a sub-vi in the future... which is why I use the switch.  You'll notice that it will eventually help to keep the vi clean.

The problem with commenting with a case structure is that your code, even code that never gets executed, has to be executable.  You can't have inclompletely wired items, or broken wires even if  the code will never be used.  So it's not really a comment, but a conditional branch that never branches.

There's always the conditional disable structure from the PDA module, which can be found in the LAVA forums. I think they warn it may crash standard LV.

If anyone wants this conditional disable, here it is.  The instructions on the front panel were not quite right.  I put the vi in my user.lib folder, and edited my palette view to include it there.  Then you have to open a vi that you want some code disabled, and also open the disable vi.  Go to the block diagram of the disable vi and copy the structure to your regular vi.  Then you can move some code that you want "commented out" into the disable structure.  This causes broken wires that you have to fix.  In my opinion, you are better off creating a case structure and wiring a false constant.

Hello!

I am really excited to inform everyone that National Instruments announced LabVIEW 8.0 yesterday.

One of the new and highly requested features of 'commenting' out code is now native in LabVIEW 8.0.

If you upgrade to LV 8, you would get conditional structure. This is a true commenting out part of code rather than wiring false to a case structure.

Hola Otoro,

By "true commenting out part of code" do you mean it wouldn't load the code, e.g., Sub VIs, into memory either? 

Don't have 8.0 yet to try it myself.

Thanks,
