Equal? Comparison on Strings - Compare Aggregates

[asbo]

Does anyone know a definition for the behavior of using the equal comparator with strings in aggregate mode? I couldn't find any circumstance where it produced a different output than when in elements mode.

Try putting an array into the comparison. The output will switch between a single boolean and an array of booleans as you switch between comparing elements and agregates.

Here's a good example:

The results are the same.

Hahaha, I came off way more green than I meant to: specifically with a string, how do the modes differ?

Same answer as with numeric data types.

I don't think you're understanding: is there a difference in behavior of individual versus aggregate comparisons for scalar values?

From the LabVIEW Help, it appears that the two modes only matter when comparing arrays or clusters. Do a search for "Using Comparison functions" or "Setting Comparison Functions to Compare Elements or Aggregates" for the official wording.

So to be clear, the question/answers are:

"With a string, how do the modes differ?" Not at all, the mode setting is ignored.

"Is there a difference in behavior of individual versus aggregate comparisons for scalar values?" No, the mode setting is ignored

Yep, that's precisely what I'm looking for. The reason I ask is Jim Kring's Case Insensitive Comparison Mode for String Equality Comparison idea got me wondering if the mode selector did anything for string values - and the fact that it wasn't grayed out when I wired two strings to it made me even more curious. Admittedly, using aggregate mode as a case-insensitive comparison is hardly intuitive functionality, but I can almost twist the logic in my head.

Thanks Djed!
