AutoLISP provides functions for handling objects. The object-handling functions are organized into two categories: functions that retrieve the entity name of a particular object, and functions that retrieve or modify entity data. See Object-Handling Functions (AutoLISP) in AutoLISP Function Synopsis (AutoLISP), for a complete list of the object-handling functions.
