Why some people say Local Variables are bad...

Have a look at this example and read on to Gerd's reply where he found race conditions.

Writing to the indicator and it's Local variable at the same time..

I guess it is to make sure that the value was actually written to it 😉

Hi Ray,

That Vi had my head spinning because its almost readable. So silly me I wander away and run right into this!

 

I did not spot any locals but I thought it should be offered as contrast to what you found.

You missed the locals on the right hand side of the image you posted:  Error & Mono Position & Mono Position (nm)

I'm sure if you keep looking you'll find more Locals..  😉

LOL Ray. One common theme in "chronic localitis" such as this is always a neat row of disconnected terminals. 😄

Yes, I often see that.  This one is not so bad... It is when you have several frames of a Stacked Sequence that it get a bit annoying.  Now why do people not bring a wire directly to a terminal??  Oh yeah... they want to update its value are many different location in the software..  yeah....  hummm...  using Locals...  hummm..

Someone has asked me to do a 'simple tweak' on this monstrosity, written by my predecessor.

The white area is 1280*1024 pixels.

Where are the local variables? Where's my microscope that I had when I was 10?

Hmmmm... Maybe it's a good thing that you can't see the local variables!

I just did a search for all instances of a variable, it came up with 537 occurrence
