Was doing some recursive directory searches and needed to combine the results from multiple directories but when a directory did not find any items I got an item of nulls. Looking at the example shown below, I don't think I should get the item of nulls.
(2 2$;:'abc de fg h'),;2#<,:;:'ww xxxx' +---+----+ |abc|de | +---+----+ |fg |h | +---+----+ |ww |xxxx| +---+----+ |ww |xxxx| +---+----+ (2 2$;:'abc de fg h'),;1#<,:;:'ww xxxx' +---+----+ |abc|de | +---+----+ |fg |h | +---+----+ |ww |xxxx| +---+----+ (2 2$;:'abc de fg h'),;0#<,:;:'ww xxxx' +---+--+ |abc|de| +---+--+ |fg |h | +---+--+ | | | +---+--+ Why is there a third item which is empty in the last case? Am I misunderstanding something about append? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
