Actually I was going to go out on a lim and try

my $num = 5; if (\&add($num) { .. } sub add { my $shift = shift; my $num2 = 10; my $sum = $num1 + $num2; if ($sum == "15") { return 1; } else { return 0; } }
But after playing through numerous attempts, I couldn't pull it off. I just figured you should be able to test the return of a sub this way, though I've never thought of trying it until now.

    Change
    if (\%add($num) { .. }
    to
    if (add($num)) { .. }

    In context, it would actually be:

    sub is_image_size_ok { my ($image) = @_; my $img = get($image); my ($height, $width) = imgsize(\$img); return $height < $max_h and $width < $max_w; } push @array, $string =~ m#stuff#g if is_image_size_ok($image);
      Thank you ikegami for clearing that up. I knew it was possible but I couldn't get the syntax to work although now that I look back, I have to wonder what I was thinking in the first place. Easy stuff.
