## Discussion

Discussion In an Apple event that specifies a script command, two four character codes—the event class and event ID—together identify the command. You use this method to obtain the event class. You use appleEventCode to obtain the event ID. For example, commands in AppleScript’s Core suite, such as clone, count, and create, have an event class code of 'core'. This code and the event ID code returned by appleEventCode together specify the necessary information for identifying and dispatching an Apple event.
