Answer 1

just off the top of my head (PHP).

$index = 0;

while(1) {
   $output_string = '';
   $base_26 = (string)base_convert($index, 10, 26);
   if (strlen($base_26) > 29) break;
   for ($i = 0; $i < strlen($base_26); $i++) {
      $output_string .= chr(65 + base_convert($base_26[$i], 26, 10));
   }
   $index++;
   echo $output_string;
}
