AppleScript: The Definitive Guide

Name

= (is) — equality

Syntax

                     operand1 = operand2
                  

Description

No coercion is performed; operands of different datatypes are not equal. Synonym is equal to has abbreviations equal, equals, and equal to.

Note

This operator is not overloaded as an assignment operator; see Section 7.1. It is not an error for a line of AppleScript code to consist of an equality comparison, like this:

x = 3

That line is an equality comparison, not an assignment! If you write a line like that, intending to write an assignment, your code will generate incorrect results that can be difficult to track down.
