Or a CountElement() function where you pass in a string and tell it a substring to return the number of occurances for.
so you could say
<cfset myLIst = "a,,b,c,,h" />
#CountElement(myList,",")+1# <!--- returns the length of my list including empty slots (6)--->
#ListLen(myList)# <!--- returns the length of my list ignoring empty slots (4) --->
I agree we can't have MM changing the definition of ListLen - way, way, way too many existing apps would break

My point was that there are at least three differing perspectives on
"proper" handling of that list. I'm not saying CF's is right, but the
simple fact that that's the way it's always been requires a little
more than "well I think" logic to instigate a change.
And since CF equates the empty string to null, and null means "doesn't
exist", then ignoring empty elements makes sense.
