The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

I think you add more to what you already have. This is similar to
filtering on dates when they are stored in 3 fields.
BTW, I would make it FOO = rather than FOO <= . That's a small point,
perhaps.

Well, "FOO <=" does slightly simplify the WHERE-clause construction
(since we're dealing with generated SQL including generated
WHERE-clauses), and in any event, it's now easily handling up to a
3-field key with no deviation from the native-RLA result (so far), and
JDBC response times (for the local database) of around 10-50
milliseconds (I have my test-jig programs fitted to display "before" and
"after" timestamps for every call to my JDBCR4 front-end).
I will, however, say that I've owned computers with less memory than I'm
allocating for WHERE-clause buffers!
Thanks. This project has been a never-ending series of surprises, most
of them pleasant, and the people of this List have been most helpful.
