Mike. Dont you think calling "DE" twice is additional overhead, even if its Minor? The less code/functions to the goal.. the faster, less buggy application you have.. Isnt that what we learned in 101/102 "C" class.. just kidding! Joe Certified Advanced ColdFusion Developer [EMAIL PROTECTED]

DE adds very little overhead as it's just doing a fast replace on double quotes as well as surrounding its argument with double quotes. This is very little processing all in all. The problem has always been IIF() itself. The fact that IIF() and CFIF are the same speed in CFMX shows that the underlying comparison code for both is either the same thing or working the same way. > I do strongly belive using the IIF right wouldnt be any slower than CFIF as > well > Eg..
