http://jsoftware.com/help/user/script_format.htm#flatten Or in other words: require 'format' flatten +-+-+-------------------------------------------------+ |3|:|dat=.

'fi', 'fo',: 'fum' fi fo fum empty m (1!:2) 4 fi fo fum <- 3*3 characters empty (flatten m) (1!:2) 4 fi fo fum a. i. flatten m 102 105 10 102 111 10 102 117 109 <- Look Ma, linefeeds! The initial ": in the function will take care of numeric and boxed data. After flattening data, I usually append a trailing LF, too.
