Example Directory cdr 004

 

 

Description

This example shows that the tail key-binding value of a Directory must first be defined before it can be accessed by the cdr function. If no tail value is defined, then the cdr function returns #void.

 

Details

(define ClassRec #{dir|Bldg: 200 Room: 34 Period: 1 } ) Returns: #<Directory 188141>

The tail value of the ClassRec Directory is defined.

(setCdr ClassRec #{dic| Teacher: "Smith" Subject: "Math" }) Returns: none
(display ClassRec) Returns: (#{dir| Bldg: 200 Room: 34 Period: 1 } . #{dir| Teacher: "Smith" Subject: "Math" })

Displays only the tail value of the ClassRec Directory.

(display (cdr ClassRec)) Returns: #{dir| Teacher: "Smith" Subject: "Math" }

Displays only the length ClassRec Directory. The cdr value is not included.

(length ClassRec) Returns: 3

Notes and Hints

The cdr is not reachable by the [] operator.
