Just to make a life a bit interesting then here is something you can run in an ijx window.
A=. 1 2 3 B=. 4 5 6 V=.'a=.y';'y+4' (3 : V) B 8 9 10 V=.'a=.y';'y+4';'b=.x';'a+b' A (4 : V) B 5 7 9 As you see here above then A and B are nouns and V is a boxed array. You change the boxed array into a verb on the fly and give it arguments. In http://groups.google.com/group/J-Programming/files the scripts threegrids.ijs and fall.ijs use this to make a simple demo of a user interface made with forms. Explained a bit in http://groups.google.com/group/j-programming/browse_thread/thread/22d3c6d5d516491e# ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
