"doto" operates on an object and returns the object that it operated on. In your case, it's the original string that gets returned. Strings are immutable so the toUpperCase call created a new string which was then thrown away. The "->" operator will accomplish what you're looking for here. It returns the result of the operations, each result becoming the input for the next:: user=> (-> (String. "hello") .toUpperCase) "HELLO" --Steve --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
