Why some people say Local Variables are bad...

The loop will never stop.. Notice that "Acquire Data" is wired to Continue if True, and it's in the TRUE case selected by...  (drum roll...) "Acquire Data"!

All values passed by Locals...  or to make matters more fun... Globals!!

This liks like an Aztec Pyramid from above. Let's call it the Aztec Coding style. :D

Joe LabView:  You need to find out who the authors of these examples are and stop them from proliferating any more code.  They are giving Labview a bad name.

LOL!! yes it looks like a pyramid..  And yes, the authors are within the thread they were found.. just follow the link.

Post any examples you find of Locals abuse..!!  or Locals causing headaches!

Well, it seems that this thread is obviously slanted to the "locals/globals are bad" side. Perhaps for balance we need a "here's good ways to use locals & globals" thread.

Here's a recent entry.

Thanks smercurio,

Yes, it is slanted...  The purpose is not to say that they are bad.. nor that they are good..

It is simply to show that in Labview, it is a common source of errors..  Mostly due to bad usage of Locals.  Same can be said with any syntax of a programming language.. 😮

If people treated Locals with respect (no abuse), then ... well... we wouldn't have to fix so much code.. 😉

However, the reason why the thread appears slanted is with the purpose of the thread, as depicted by the title.  🙂

Multiple Locals and Multiple Loops..  A mix for success..
