Right; I hadn't considered that.

Ah, good, then I'm not completely insane. :-) I had switched from values to each on an ETL project last year, and I was remembering that I'd done it for speed reasons, but now that I think about it, it may very well have been for memory purposes instead.

Thanx for the clarifications.
