To EXIST or to NOTEXISTs
I started seeing threads pop up about using "EXISTS" and "NOTEXISTS" in filters and was surprised to see that the capability, for lack of a better term, existed. The occasional question came along over the years about this sort of reporting, to which I replied "Not that I'm aware of". Apparently, I was unaware and I'm probably not the only one.
Searching for documentation in the help site yielded no results, and I found it difficult to interpret the various examples, even though they worked wonderfully! I accepted the challenge and thought, what a great opportunity to figure this thing out and share the outcome.
Have a look at the "How To" procedure and let me know what you think of the approach. Also, please have a look at a few of the "Example Text Mode" entries so far.
