I tried to prove above to my co-workers and failed - tests of code with extra ## and without didn't show any speed difference. Even with 10000 of cfsets there was no difference I could notice. On the other hand, cfif is faster than cfcase.

For example, the following code is valid:<br><br><cfset dogs=3><br><cfset cats=9><br><cfoutput>There are #dogs + cats# pets on hand</cfoutput><br><br>(Note that code in of this form mixes logic and presentation, which may not be desirable from the point of view of style and ease of understanding.)<br><br>However, in a cfset statement or function, you must not use pound signs around the expression. For example, the following line generates an error:<br><br><cfset foo=#1+2#><br><br>Instead, use <br><br><cfset foo=1+2> halL 1 1 2004-01-16T08:19:15 http://livedocs.adobe.com/coldfusion/6.1/htmldocs/exprea13.htm#5282 #1+1# will work in CFMX! <br /><br />Why is it recommended here not to do that? Is it leftover from previous version documentation or is there some hidden reason? JeffHouser 0 0 2004-01-15T14:43:04
