And here my code:

   print "File level $level : $PRESENTLEVELFILE\n";
   $level++;
   open(PRESENTLEVELFILE);
    while ($leafline=<PRESENTLEVELFILE>){
    print "Leggo $leafline\n";
    chomp($leafline);
    if ($. == 1){
      if($PRESENTLEVELFILE =~ /^0*/i){
        open(FINAL,">$finaltreefile");
        print FINAL "0 $leafline\n";
        close(FINAL);
