+/table will sum that table <table will put that table in a box > Also, in the Dictionary for Cut it describes the rank as "_ 1/2 _". What > does the "1/2" mean? Needless to say, I still have a long way go to fully > understand Cut. That dictionary page says: The 0- and 3-cuts have a left rank of 2; the 1- and 2-cuts have a left rank of 1. Cut verbs will cut a table into pieces. How they cut tables up into pieces is controlled by the right conjunction argument to ;. (a small integer) and what they do with those pieces is controlled by the left conjunction argument to ;. (a verb). Using < is an excellent way to visualize this process, so I think you are on the right track. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
