My rule is always use 13: unless it doesn't work or doesn't give the result I want.

I would have expected a dyadic 13 to produce results like its 4 counterpart and monadic 13 to produce results like its 3 counterpart. 5(4 :'y++y')2 3 4 NB. These 2 produce different results 4 6 8 5(13 :'y++y')2 3 4 9 11 13 (3 :'y++y')2 3 4 NB. These 2 produce same results 4 6 8 (13 :'y++y')2 3 4 4 6 8 --- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
