Hi Folks,concat#3 is an expression that returns a function item. You need it if you are going to store the function item in a variable, pass it to another function, return it from a function, or do other things that you can do with run-time values. You don't need a run-time function item if you know statically what function to call and if the only thing you want to do is to call the function. Michael Kay Saxonica
