I love forks, and they are useful for everything!!!! to use a traditional language example
a =. (x) f y NB. function of 1 or 2 arguments passed to function. assign to temp var a b =. (x) g y NB. Other function using passed arguments c =. b h a NB. combine the above 2 results with h function. NB. could return c here return. (x or y) h2 c NB. combine previous result with either original x or y arguments with the last step being the y argument, this is the equivalent fork (] h2 g h f) the main reason you have intermediate results in other languages is that you need to combine them later with another function. Forks provides a clean and terse way of doing so. ----- Original Message ----- From: 'Dan Baronet' via Programming <programm...@jsoftware.com> To: "programm...@jsoftware.com" <programm...@jsoftware.com> Cc: Sent: Wednesday, July 16, 2014 4:26:38 PM Subject: [Jprogramming] trains I am looking for good examples of use of trains. Apart from the classic +/ % #, I can't think of many more. Anyone with some examples? They can be of any length. /Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
