Re: SETLL *START and %EQUAL

I believe that SETLL never points _*at*_ a record, it always points to something "between" records - this goes back to Bob Cozzi's books on RPG, they show this behavior in a diagram, as I recall.

Setll is said to position just before a record so the next read reads the expected record. In fact, you can't physically read before the first record, or after the last one (in case of setgt). I assert, setll and setgt just set a flag so the next read(e) behaves as described.

To me, it sounds like some kind of a "children's lie" — to have an easily comprehensible explanation for the given behavior. :-) It's good enough to explain what's going on for most of the use cases, though.

Maybe that helps with the behavior you are seeing. I admit things feel kind of wonky, though.

Indeed. :-)
