Hi Jo! JES>In an ideal world the special MagiC-messages to AESSYS should also be JES>supported. These could be handled by the same code that handles JES>appl_control(). I started to write a TSR that provides appl_control() to MagiC (via these special Messages) so there will be no need to support these undocumented messages when I have finished it Bye Joerg
