Regarding rotl/rotr, that was a typo in the example; they rotate the top three items left or right, I find Forths choice of 'rot' arbitrary but that may be a consequence of how the pieces fit together in Snigl. And I agree, the sum of 0-7 is still 28 :) Another typo. Thanks again, this really helps. The plan is to turn all examples into actual tests and generate the README using Snigl eventually, but the required features are not quite there yet.
