Hi George,

For a million loops, something like 1.4 seconds versus 1.2 seconds, consistently and with nothing else running.

I think I mentioned this earlier ... I have known IF...ENDIF to be faster for quite some time now. I thought it was common wisdom and I was surprised when I saw messages stating IIF was faster. So I just took a couple of minutes and whipped up this example.

You can try the code yourself for further validation.

Bottom line ... I have no inside knowledge here, but I have always believed that for all versions ... as long as IIF has been around, IF...ENDIF has been faster.

Guy
