Straight from the online documentation:
--------------------------
Passing arguments
ColdFusion passes arrays and simple data types including integers, strings,
and time and date values into the function by value. It passes queries and
structures into the function by reference. As a result, if you change the
value of a query or structure argument variable in the function, it changes
the value of the variable that the calling page used in calling the
function. However, if you change the value of an array or string argument
variable in the function, it does not change the value of the string
variable in the calling page.

I shoulda looked it up sooner. Sorry... <grins>

Subject: RE: Passing variables in UDF
I was wrong in saying that an array was passed by reference. I just tested
it out and it is passed by value. I was assuming based on the normal array
function results that it would be. I hate when things are not 'standard'.
Causes an error
<CFSCRIPT>
function test(aVar)
{
aVar[1] = "name";
}
aVar=ArrayNew(1);
test(aVar);
WriteOutPut(aVar[1]);
</CFSCRIPT>
works
<CFSCRIPT>
function test(aVar)
{
aVar[1] = "name";
return aVar;
}
aVar=ArrayNew(1);
aVar=test(aVar);
WriteOutPut(aVar[1]);
</CFSCRIPT>
