Um. I think that you have pretty much hit on the definition of a UDF --
it's a user defined function. Functions are called with parameters and
return a result (unless you write them wrong, in which case they hang :-).
And yes, you could use an include file repeatedly for this. However, I
prefer syntax like:
#TrimToWord(query.textfield, 500)#
to:
<cfset string = query.textfield>
<cfset length = 500>
<cfinclude template="includes/TrimToWord.cfm">
Of course, you could also write this as a custom tag. You could put a
snippet in your library and just edit what variables it works on. There are
a half-dozen ways to do similar things, I'm sure. I guess it's all in the
way you think and what makes the most sense to you.

: : Tony,
: :
: : Pre CFMX using a block of cfscript to set some variables or perform
: most

: : have a block of cfscript and set 10 variables compared to 10 <cfset>
: : tags the only difference would be the white space between the <cfset>
