Chapter 15. Operators

An operator is a token that transforms a value or a pair of values to produce a new value. These transformations are operations, and the values operated upon are the operands. An operator with two operands is binary; an operator with one operand is unary. This chapter lists the AppleScript operators and explains what they do, with special attention to implicit coercions performed by the operators. It also talks about parentheses, because they help determine the effects of the operators. Finally, there's a section on the differences between what happens when AppleScript performs an operation and when a scriptable application performs it.

(For the coercion operator, as, see Chapter 14; for the object containment operator, of, see Chapter 11.)
