The plussign (+) works for (1 + 1); (1 + 1 2); (1 2 + 1 2); (1 2 3 +/ 1 2 3) The latter (+/) produces a table. The operation (o=.3-3|+) works for (1 o 1); (1 o 1 2); (1 2 o 1 2); (1 2 3 o/ 1 2 3) But (o/) did not produce a table. The workaround is (1 2 3(3-3|+/)1 2 3) with the slash inside.
I don't understand. Please explain. Thanks! Bo. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
