In short, the whole idea behind blocking remote function calls is to NOT have to implement an event handler, but have a blocking remote call wait for the response from the Server, then return the result.
Here is the

Everything else you need to know about RTC remote functions is
explained in these few topics.
For a detailed explanation on method parameters, please check the HELP file or comments in the interface section of each class.
