Hold up your right hand with its back toward you and number the forefinger through little finger 1 through 4. (I suppose the thumb has index 0.) Now try finger tapping this pattern:
1 2 3 4 3 2 1 2 3 4 3 2 1 2 3 4 3 2 1 2 3 4 3 2 Write a J expression to produce this pattern. --Kip Murray -- Sent from Gmail Mobile ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
