Can anyone help me to understand where I am going wrong? e=: 2 7 1 8 2 8 1 8 3 pi=: 3 1 4 1 5 9 2 6 5 isecn=: ([: /:~ [: ~. e. # [)"1 NB. Intersection of the two sets e isecn pi 1 2 3 pi isecn e 1 2 3 isecn/ e,:pi 1 2 3 isecn/"1 e,.pi
This last sentence give me 9 blank lines. I expected and wanted 1 2 3. Is my view of rank and frames too simplistic? Regards Graham ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
