jdatafn3 is a file with structure. For example, you could have done: jdata3 =. i.5 5 5 instead of jdata3 =. i.125 So J has to have a description of that structure contained in the file. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
