Now that looks like simple nested iterations, not permutations: Array streamContents: [:s | #('A') do: [:a | #('a' 'b' 'c' 'd') do: [:b | #('1' '2' '3') do: [:c | s nextPut: {a. b. c}]]]] - Bert - _______________________________________________ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
