^t. %@! This is all that t. does -- it's up to you how you use it. %@! i.6 1 1 0.5 0.166667 0.0416667 0.00833333 1 %@! i.6 _ 1 0.5 0.333333 0.25 0.2 The first sentence is an example how this mechanism was intended to be used. The second sentence is just coincidence -- the result of t. was not designed to deal with a left argument. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
