You do know that an SQL VIEW does not include any index automatically,

Right, and if there's a process for attaching an index to an SQL VIEW,
so that RLA can access it by key, I don't see it, and if I knew about
it, I don't remember it. (There certainly OUGHT to be one, if there isn't!)
One difference: when I check the number of records, the DDS LF returns
the number of records in the PF (10, for the "guinea pig" library I was
given), while the SQL VIEW returns the number that the WHERE clause
finds (only 1).
But other than that, I just ran a trace of everything that goes on
between returning from the SETLL-equivalent call, and issuing the
READ-equivalent call, and in some 150-odd instructions, the only
difference is an extra iteration of a loop that massages the
aforementioned total number of records, so it can be displayed.
I'm now going to do something in RPG (thanks, Chuck), that will
hopefully simulate the point-of-failure, to see what *it* does.
