The edition doesn't matter, the core j language had been stabilized 2 decades ago. You only need to understand a few key concepts. J is in fact a very simple language when compared with c++, java etc.
PS. J general forum is mainly used for discussion of installation issues. It is unfortunate that its name is misleading. When unsure, post to the j programming forum.

Oh—I really didn't mean the book itself, just that edition of the book, since I figured the one on the website/in the addons has been updated since then. But maybe that isn't true; the one on the website actually says 2001-5-3 versus 2002-09-10. -- Daniel Lyons ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
