If you wanted step 2 for an end in itself, you might do something like this: N=: <.@o. 10^50x ,' ',.":N 3 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 2 3 8 4 6 2 6 4 3 3 8 3 2 7 9 5 0 2 8 8 4 1 9 7 1 6 9 3 9 9 3 7 5 1 0 If the first space was undesirable, you could then drop it... }.,' ',.":N But, as other people have demonstrated, it can be wise to omit intermediate goals that you do not need. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
