expression1 <> expression2
Deprecated since Flash Player 5. This operator has been deprecated. Adobe recommends that you use the != (inequality) operator.
Tests for the exact opposite of the equality (==) operator. If expression1 is equal to expression2, the result is false. As with the equality (==)operator, the definition of equal depends on the data types being compared:
expression1 : Object - A number, string, Boolean value, variable, object, array, or function.
expression2 : Object - A number, string, Boolean value, variable, object, array, or function.
Boolean - The Boolean result of the comparison.
