I've given some long winded explanations. I'll try a brief one. It encourages and fosters thinking from applying functions from left to right.
J is built with "thinking" about building solutions from right to left. Do the first thing. Apply the next command by placing it to the left of the previous result and so forth. The final result can be "read" from left to right. But the building of the result is best done from the right and then to be clear you can insert [: to insure that you are getting the meaning you wish. Then if you can get the result you want, use f=: 13 :'expression in y or x and y' When you display the function it will be a tacit expression. Hope this adds to previous ways I tried to explain my reason.

Why should we avoid @ ? That's like posting a Unix shell-scripting challenge, and saying "avoid | (use file redirects instead)". -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
