Well, not that I can think of (Martin?) - just a way to get a result back from the j verb when the requested host expression failed. Yours is shorter and very nice - even a useful result if one checks for numeric result (impossible as a result of remote execution - I think) indicating an error. Maybe not as handy if building a result in jspace by catenating successive calls, but I don't remember ever doing that. Since the standard error comes back in addition to the obverse result, I would be inclined to make the failure result 2: (or something other than 0 which usually indicates all ok -- but that it a minor matter of taste.) Thanks for the nice cleanup/improvement! - joey ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
