After reading your comment, I've nervously put the routine in a test harness. It clocked at 0.054 Ms. per execution. I have to say that when I'm optimizing, I go after bigger fish!

It's just such small-fry that used to choke the server I took over because there were many such small fish that got executed hundreds of millions of times per day. If you consider the overall improvement is 3:1, that's not bad especially considering the number of executions over the course of the day.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
