Error Numbers and Error Messages

This appendix describes error numbers and error messages provided by AppleScript and OS X.

AppleScript Errors

An AppleScript error is an error that occurs when AppleScript processes script statements. Nearly all of these are of interest to users. For errors returned by an application, see the documentation for that application.

Operating System Errors

An operating system error is an error that occurs when AppleScript or an application requests services from the Mac OS. They are rare, and often there is nothing you can do about them in a script, other than report them. A few, such as "User canceled", make sense for scripts to handle—as shown, for an example, in the Examples section for the display dialog command.
