Re: Rook question

Try this:

sub total{
        my $sum = shift(@_);
        foreach (@_){
                $sum += $_;
                }
  return $sum;
}

add $_, not @_
return $sum
Add trailing } to match braces

Awesome! Fixed the problem--thanks much! I didn't know if Perl associated the default $_ while moving through the indices of @_.	[reply]

The mechanism of action is the foreach loop. It's just as happy aliasing `$_` to elements of `@this`, `@that`, and `@the_other` as well. In this regard, `@_` isn't special; foreach is. perlsyn Dave	[reply] [d/l] [select]
