That's what <cfparam is for, isn't it?

Subject: Efficient way to handle undefined variables
What is the best/most efficient way to handle a scenario where you're
populating variables from other variables that may or may not exist. If
they don't exist, an empty string should be assigned. I wrote a little
function to do this with a simple if statement inside:
If (isDefined("inVal")
{
outVal = inVal;
}
else
{
outVal = "";
}
Is this the best way to go about this? I'm going to end up wrapping
quite a few variables in this function, that's why I'm curious (I'm
puling in an XML that potentially has MANY optional variables).
Thanks,
Rich
