Application Scripting Errors

An application scripting error is an error returned by an application when handling standard AppleScript commands (commands that apply to all applications). Many of these errors, such as "The specified object is a property, not an element" , are of interest to users and should be handled. Developers can define new application errors in the -10,000 range for their applications.
