I don't understand this bit of the documentation about EVENTS:
One or more clients may choose to "subscribe" to events from a server object by executing the EVENTS FROM statement. The subscription is terminated by execution of the EVENTS END statement. When the server executes RAISEEVENT or OBJECT RAISEEVENT, all clients which have unsubscribed to these events are called. PowerBASIC servers support up to 32 concurrent client subscribers per server object.
