The output is kept in an output buffer until it's flushed (either because the buffer is full or by request). println includes a call to (flush) (if *flush-on-newline* is true, which is the default). In your case, you can use an explicit call to (flush) when you want to be sure the user has seen what's been printed so far. --Steve
