check to see if it is empty (whatever that means :D) `$correction = $data_pair->{value} if exists $data_pair->{value} and # could be undef defined $data_pair->{value} and # at least "" length $data_pair->{value} and # has length $data_pair->{value} and # has true value $data_pair->{key} eq 'correct';` [download]	[reply] [d/l]

empty

$correction = $data_pair->{value}
    if exists $data_pair->{value} and    # could be undef
      defined $data_pair->{value} and    # at least ""
      length $data_pair->{value}  and    # has length
      $data_pair->{value}         and    #  has true value
      $data_pair->{key} eq 'correct';
