MSIR.0801 READ SCREEN encountered in NOSCREEN mode
A Janus Web Server port was defined with the NOSCREEN parameter, presumably to prevent accidental entry to Janus Web Legacy mode, but the application running on the port issued a READ SCREEN. Either the NOSCREEN setting is working as expected and has caught an accidental READ SCREEN or there is a real need to use Janus Web Legacy support on the port. In the former case, correct the application to prevent a READ SCREEN from a web request -- the $web function makes it easy to detect when code is running on a web thread. In the latter case, either remove the NOSCREEN parameter from the port definition or add a SCREEN parameter to the JANUS WEB ON rule for the URLs which need to use Janus Web Legacy support.
