You missed reading in the argument for your subroutine. hint: @_

    Just tried that, now get "-- 1".
    sub changedate { my $year=0; my $month=0; my $day=0; ($year, $month, $day) = split(/-/, @_, 3); return $day."-".$month."-".$year; }

    It's something but it still aint right :)

    Thanks, Alex
      Just to clarify something here, you got the correct answer for what you asked perl to do. split() expects a scalar, which caused @_ to be evaluated in scalar context. In this case that was 1, since you where sending but one arguement to the subroutine. split() applied your regex and returned (1,undef,undef).

      I might suggest you read up on -w and use strict; as well - it would have at least flagged a warning on that line. It will also save you a lot of grief sooner or later.
