Hi, Have a look at the functions: line-seq and clojure.java.io/reader I think you want something like: (line-seq (reader "c:/test.txt")) This returns you a lazy sequence of the lines in the file, which will only read the file once, caching the lines that have been read in the seq. The sequence is immutable, though it will only read the lines from the underlying file as required. If you are interested in how this works, try (source line-seq) to see the code. -- Dave -- You received this message because you are subscribed to the Google Groups "Clojure" group.
