Raul suggested: > GetPrices=:(0 :0)&(4 :0)
I would warn you away from this pattern if you use or intend to use the J debugging facilities. The dyad within the monad GetPrice is anonymous, and consequently atomic from the J debugger's POV; hence undebuggable. That said, I've found this a useful idiom in many cases. -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
