b=. 2 2 $'abcd' copy=.13 : ',./ > x $< y ' NB. copies the box side by side 3 copy b ababab cdcdcd 4 copy b abababab cdcdcdcd
Maybe, I could use under(as in 13 : ',./ (x&$)&.< y') but the final form isn't tacit, which is not a big problem; however I'm interested in knowing other possibilities. Any suggestions? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
