To pound or not to pound in ColdFusion

Most Cold Fusion developers overuse the # character. Here are a couple of rules that will help you decide when to “pound” your variables:

#‘s are never needed around variable names used in Cold Fusion tag attributes, unless they occur within an attribute string.
#‘s are always needed around variables that occur outside of (or in between pairs of) Cold Fusion tags. In other words, variables that occur within a block of text (e.g. SQL code between <CFQUERY> and </CFQUERY>, text in a <CFMAIL> body) must be surrounded by #‘s. Similarly, variables with a string (text within double quotes) must be surrounded by #‘s too.

And those are the only places to use them.

Tell me about it! I’ve lost count of the number of times I’ve had to demonstrate the correct use of pound signs in CF.

This is a good article on the subject by Ben Forta: http://www.defusion.com/articles/index.cfm?ArticleID=26

Thanks for the link Martin. I already have it in my bookmarks. I thought that posting the two rules that Ben had written about would clear up any confusion surrounding the use of pound signs in ColdFusion.
