Example Pair isType 021

 

 

Description

This example shows that the AIS only has Pair and NOT List as the symbolic name for the Pair Data Type. However, Lists are considered also as Pairs because a List is really a collection of pairs chained together.

 

Details

(setq X '(employee name job salary ) ) Returns: #<Pair 197815>
(isType Pair: X) Returns: true

The container X contains a Pair because a List is really a collection of pairs chained together.

(isType List: X) Returns: false
