In J frontends, errors were trapped by wdhandler or event handler and the frontend implements the necessary codes to get the name of verb where an error was raised.
I imagine it would also be the responsbility of vb/c# interface itself to implement similar codes for error handling. -- regards, ==================================================== GPG key 1024D/4434BAB3 2008-08-24 gpg --keyserver subkeys.pgp.net --recv-keys 4434BAB3 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
