You're right, Loyd. I shoulda actually TRIED brute force first.

In ILE RPG (I honestly didn't care WHAT I needed to use, as long as I could get it done!), scanning the entire 1400-record-ID window of interest (200 to 1600 on a 7-digit key) with SETLL, and counting the key values without records, returned a count of 212 in less than a second of execution time.
