Guy,

Hmmm...I could've sworn that at one time I read that IIF() was faster. Maybe it was "conventional wisdom" that no longer applies.

I do, however, have a couple of questions.

First, what were the actual results?

Second, how many times did you run the test and were the results consistent?

Third, did you have anything else other than VFP running at the time?
