    Thanx, and a happy new year for you too! 8 )

    I have to admit I was confused by your example, it's important to understand that printf takes his parameters by reference and not by value!

    So it's possible to still influence $_ in the last parameter with effect for the first!

    Very insightful, thanx a lot!

    Cheers Rolf

      Well, it's a bit complicated, but yes, all perl functions take parameters by reference.
