    You have written my @sorted = sort_try (@unsorted); but your sort_try sub doesn't return anything (and it also ignores its arguments but that's a different matter). Try reading perlsub for the basics.

      thank you very much that was really nice from you i got my answer :)

        You may want to think a little about the sorting algorithm used. Gnome sort is an example of a stunningly bad way to sort. Now you have a working example, have a quick google and look for better ways. I'm sure we can help with any attempts to code other methods.

        Cheers,
        R.
