Predefined Variables

Predefined variables are variables whose values are supplied by AppleScript. You can use them in scripts without setting their values. Predefined variables are global--that is, you can use them anywhere in a script.

For a summary of AppleScript's predefined variables, see Constants and The Language at a Glance.

Note

Although AppleScript does not prevent you from setting the values of predefined variables, you should treat predefined variables as constants--that is, you should never change their values.
