Actually, if you want to be really precise, then the KiXtart Golf score is the number of bytes in a non-UNICODE text file that only contains the appropriate UDF and that is still runnable through KiXtart.
For example
code:
function anagram($) dim $a for $a=1 to 10 next $anagram=0 endfunction

is a valid KiXtart script and the filesize equals the KiXtart Golf score. Note that there are no CR/LFs and/or excess spaces...
