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.

No argument with reading the manual, but I'm really comfortable with how
a CHAIN works. And I *know* that a CHAIN can never update the
database. There are some things you can know, Mihael. That, by the
way, is one reason I've always been a little leery of SQL. Talk about a
black box - you're never quit sure WHAT that engine is doing.

No, I don't know what it (SQL) is doing and most of the time I am quite comfortable with that. It should just do it. I don't think that I would understand what it would do even if it would explain it to me. So a black box is really ok for me. I just want to use it. I don't necessarily want to understand the internals. So I don't try to assume too much about those black boxes.
