That Depends on the type of variable. - structures, cfc instances and java object instances are passed by reference. - simple variables (string, numeric, etc) and arrays are passe by value.  Arrays are passed by value as shallow copies (meaning any structures or objects inside the array are passed by reference). Right on!   - Is this value/reference outcome dependent on the CFC method's specified returnType (are objects returned in a different way from, say, arrays or structs?) Nope it's dependent on the type of variable as described above.  Structures are returned as a reference an string is returned by value. Chris is correct. - Is there an Adobe TechNote or similar doc on this subject that we've overlooked? Probably. I'm sure it's described somewhere in the doco whether it is a TechNote or LiveDocs - you'd have to search for it. - Has this behaviour changed between CF versions or hotfixes? Don't think so but could be wrong. I don't think you are wrong - IIRC, most languages pass variables around in a similar method to CF.  Until recent version IIRC, php suffered from passing objects by value instead of ref.  What a pain!  (As you can see, I don't do much PHP)... -- Peter J.
