What would be the scope of a UDF then? say udf.foo or function.foo?

Is that all the function keyword
Your reading me correctly. A UDF is a 'system symbol' like any variable,
object reference, etc. This means it shows up in an IsDefined() call and
even has its own function (IsCustomFunction()). The example below shows a
simple UDF and it's aliases. One of which is a server variable.
CFSCRIPT

Yes. Consider this:

Looking forward to the UDF's at any rate... thanks for the info!

Structure your ColdFusion
can you do inside UDFs?
Thanks

In CF 5 the answer is yes.
CFSCRIPT
function StringLimit(string, length)
{
if (len(string) GT 8)
return Left(lname, 8);
else
return string;
}
/CFSCRIPT
I already know the answer to this, but I
This is possible in ColdFusion 5 which will be released soon. For an set of
examples on UDF, see www.cflib.org.

I already know the answer to this,
User-defined functions (UDFs) will be available in ColdFusion 5.0, which
should be released in the near future. The syntax will not allow you to call
tags from within the custom function, only cfscript elements and functions.
For example:
cfscript
function StringLimit(thestring,length) {
Awesome! Thanks Michael...! Will those user defined functions be included in
a global functions page or how are they accessed? Say you have 50 user
defined functions you wouldn't want to include them all, right?

The normal operation is to have your UDF either on the same page as you need
them or in a CFINCLUDE. If your especially evil then you can load them into
server or application variables in an initialization page and then use

Why kill all the cool speed increase you get from a UDF by putting it in a
custom tag? A 'header library' is acceptable in most languages so putting
CFINCLUDE template=/cfide/library/libdebug.cfm
in the application.cfm is
the ones you want.
Kind of like including header file in C.

What about putting them in a custom tag and then just calling the UDF's
