Hi All, Is there a tacit way to copy forward the number which occurs before the first zero in any sequence of zeroes into the positions of those zeroes?
E.g. Is there a tacit f which does this: 0 f 1 0 2 3 4 5 0 0 0 4 3 2 4 1 1 2 3 4 5 5 5 5 4 3 2 4 Thanks, Matthew. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
