Thanks Bo, I am actually following the 'Learning J' book that is on the J website. its been good so far, but i've been getting a bit confused with the '&' verb and '@:' verb and what makes them different (they are verbs right?). Its funny because i was bored of math class in high school and was one of those kids who "skipped" a lot, but using a language like J has made me fascinated with what is possible.
