This little function doesn't jive in LV2016 for me. The top equality check is producing an array of size 4, whereas the middle and bottom equality checks are producing arrays with size 1. I end up with a 2-D output array which seems like 'none of the above'. What am I missing, please?

Hi Madmanguruman

The key here is the Comparison Modes assigned to the Equals? nodes, through the right click interface of each node.

Check out the snippet below, I have configured the top Equals? to Compare Elements and the bottom to Compare Aggregates. 

NOTE:  There are visual clues, the thickness of the Boolean wires output from the Equals? nodes (are they an array or a scalar).  Have a look at the original question to identify the difference between it and your snippet.

Got it! One of those things where mouseover is beneficial. Thanks for the clarification.

Thanks to this blog, I was able to pass my CLAD exam on the first crack. I've been using LabVIEW full-time for around 1 1/2 years, part-time for around 5 years. I took the online versions of Core 1 and Core 2 starting in January and did the practice exams as well.

Hi Madmanguruman.  Nice one, congratulations.  If you get a spare 5 minutes could you comment on your CLAD exam experience here?
