There is no way to know the address of the object being assigned the
result of the function call.  I don't know of any language that would 
provide this. Note that the function result might not be stored into a 
variable at all.

You need to change your function into a procedure with an OUT parameter,
then use 'Address on the OUT parameter, if knowing the address is
essential.
