   if ($debug) { print "processing: $line<br />\n"; }

   $ret = substr($line,0,$chars);
   $count = $chars;

   while ($char != " ") {
      $char = substr($line,$count,1);

      if ($char == '') { return $ret; }

      if ($debug) { print "$count: '$char'<br />\n"; }
      $ret .= $char;
      $count++;
   }

   $ret .= "<br />\n";

   $mystr = substr($line,$count);
