Dear Dan, i do thank you and feel grateful to you and the fellow J ers for your amazing answers,
you must see the irony though, terse J, very succinct J, and very very long lists of options for doing simple things otherwise. It seems that J ers do J for the love of J and that it can be a near full time avocation. thanks indeed, D PS This very often feels like some sort of therapy sessions ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
