XYZ system is a CASE Environment based on the linear time temporal logic proposed by Manna and Pnueli, whose kernel is the temporal logic language XYZ/E. XYZ/ADL (animation description language) is its application in the animation field. Dr. Ma put forward the SDL/A (animation script description language) oriented towards the TLAD (temporal logic based animation description model). The XYZ/ADL language introduced in this paper is expanded from SDL/A on the base of the XYZ/E framework. It takes the object-oriented programming basic structure of XYZ/E-Agent as the main description unit.The agent is constituted of a process and a corresponding package.The package part serves for encapsulation and the process part for communication.Therefore it is more convenient to describe the action feature of the complicated actors (including the parent-child actors) and the concurrency among the multi-actors,and in a unified logic system it implements the actor's action abstraction and the movement's abstract specification,which is adaptive more generally.
