Public assignment (i.e. using =:) to a name that is privately defined (i. e. with =.) is a domain error, and is the only way to get domain error on a simple assignment.
Thank you for advice! I would like the error messages to be more detailed. Often I really can’t understand what exactly the error is. Sergey ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
