# Example Pair isIdentical 017

#### Description

The isIdentical function compares the object ID of the Pair arguments. In this example the copy and setq functions are used to illustrate how the isIdentical function behaves.

#### Details

The first Pair.

 (setq A '( 1 2 3) ) Returns: #

The second Pair.

 (setq B ' ( 1 2 3) ) Returns: #

The copied Pair has a different Object ID.

 (setq C (copy A)) Returns: #

Pair D has the same Object Id as Pair A.

 (setq D A) Returns: #

A and B do not have identical Object IDs.

 (isIdentical A B) Returns: false

B and C do not have identical Object IDs.

 (isIdentical B C) Returns: false

D and A have identical Object IDs.

 (isIdentical D A) Returns: true
