No, and you don't have them, these are caused by your script.
The line starting with ->, it's what mIRC is sending to the server and the server answer back with the raw 421 indicating that you sent an unknown command to the server. I'm sure you recognize that command, it's your raw event definition.
This means that your script has a { } mismatch, it's missing a closing } at some points so it continues to execute the new line.
/raw is a valid command which sends the data to the server as a command.
And indeed, your first raw event is missing a } at the end
