Frankly I've no idea on the grounds that I simply cannot be bothered to 
look, and at this time of the night/early morning I'm not inclined to 
play guessing games.  Perhaps the OP would be kind enough to provide the 
requirements and his/her code in one hit, the answer can be one hit, and 
we happily move on to Boxing day.
