5!:0 and `: 6 can produce conjunctions too. I can't think of a way to produce a non-trivial case without using 2 :, though. y =. & ay =. 5!:1 <'y' ay `: 6 & ay 5!:0 & 5 (ay `: 6) + 5&+ 5 (ay `: 6) + 10 15 The AR operand to 5!:0 and `: 6 is a noun and can be created by any means, not necessarily 5!:1. ad =. < (,':') ,&< ((,'0');2) ,&< (,'0');2 1 $' &' ad +-----------------+ |+-+-------------+| ||:|+-----+-----+|| || ||+-+-+|+-+-+||| || |||0|2|||0| |||| || ||+-+-+|| |&|||| || || |+-+-+||| || |+-----+-----+|| |+-+-------------+| +-----------------+ ad `: 6 +-+-+-+ |2|:| | | | |&| +-+-+-+ 2 : 0 & ) + (ad `: 6) - +-+ |&| +-+ & Henry Rich ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
