st: Cohen's Kappa in Stata 2 raters 3 categories 200 cases

Hello all,
I need to calculate Cohen's Kappa for two raters in 200 cases. My problem is that in some cases the rater was given the possibility to rate 0, 1 or 2 (0 min, 1 average, and 2 max).
First, I'm wondering if I can calculate Cohen's Kappa overall for the total score (a sum of all the 200 cases) and for each case.
Secondly, assuming this can be done, how do I structure the dataset?
Thanks a lot in advance,
janicke
