I know i can partition a list like this: list=:_1 4 6 8 3 5 8 _1 7 4 <;._1 list +-----------+---+ |4 6 8 3 5 8|7 4| +-----------+---+
Here a new partition is made when encountering a _1. But what if I want to apply an operation on every 3rd item in list? Do I need to write a verb for doing that? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
