Hi Mark, What the documentation means is that you give dochars a "name" for a variable and a string to process. It then iterates over each character in the string using 'name' as a variable representing the character, so that each of the (0 or more) forms in the body can "do" something with the character by referring to "name": (dochars [ch "Is this not pung?"] (print (Character/toUpperCase ch)))
However, what you probably want to do is use 'map' to transform one string to another: (map (fn [ch] (Character/toUpperCase ch)) "Is this not pung?") => (\I \S \space \T \H \I \S \space \N \O \T \space \P \U \N \G \?) But now we've wound up with a sequence rather than a string specifically, so we need one more step: (apply str (map (fn [ch] (Character/toUpperCase ch)) "Is this not pung?")) => "IS THIS NOT PUNG?"
