Hi, What would be the recommended way to do this , say replace every element that is odd to '_1' ?
0 1 2 3 4 => 0 _1 2 _1 4 I tried to under stand the 'm } ' verb but don't know how to generate the m based on a predicate. similarly how about replace the first n with _1 ? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
