what does faster mean? Is this a step ladder to the moon sort of thing?

Rob,
 
Let me be clear: I don't think using SQL is silly (I use it a lot, even
through CLI); I just think using SQL for reading one record (oops, tuple) at
a time is silly.
 
The BPCS situation you describe sounds like an ugly problem to me. Solutions
to ugly problems tend to be ugly themselves, whether they use SQL (how do
you define the host variables?) or native RPG access (of course it can be
done).
 
As for SQL being faster: I know there are situations where SQL is definitely
faster, but I would be mightily surprised if retrieving one record with a
SELECT statement would be faster than an RPG CHAIN. But I must admit I never
tested that.
