Re: Split - Not using arguments

[lemming]

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

[fastkeys]

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.
