$ nice /usr/local/j64-602/bin/j NB. Goal: append two rows of _ to an array NB. Result: consumes all memory (_&,~)^:2(8 12$2 8 2#_ _1 _)

(,&_)^:2(8 12$2 8 2#_ _1 _) Thanks, Dave. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
