Is there and easy way to check for keyword arguments passed to the main program while in the event handler. For example, I would like to pass the option to debur or not via /debug. In the main program I can use keyword_set(debug), but this is not recognized in the event handler. I can use options such as system variables, but is there an easy way? Can I pass arguments to the event handler for example?
