Personally, I use the ValueOrSpace() UDF from http://www.cflib.org. <cfif Len(variable)> is one I use quite often as well. I use ValueOrSpace() when say, populating a table from a db query, and Len(variable) when I'm deciding to do one thing or another with processing (like form processing).

There seem to be a few options -- <cfif isdefined(#variable#)> #variable# </cfif> or <cfif len(#variable#) GT 0> #variable# </cfif> or <cfif #variable# IS ""> #variable# </cfif> Is one of these better than the others for dealing with text values? I understand that IsDefined should be locked; I assume that is not the case for the other two.
