I don't know how I would find such code, though I can imagine having written it. So, instead, I'll describe an example where I might have used this pattern: game logic where the verb advanced the game state (returning an updated game board, or a win/lose/draw game over message). (And, here, depending on what all I was using the gerund for, one of the challenges would probably be making apparent to the reader the relationship between the decision logic (@.w) and the organization of the gerund (u`v ...).) -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
