ＣＡＳＥＣ＋＋语言是面向对象的ＣＡＳＥ环境青鸟Ⅱ型系统中设计、实现的一个与Ｃ＋＋完全兼容并支持永久对象的面向对象程序设计语言．在青鸟Ⅱ型系统中，它是对象管理系统ＯＭＳ（ｏｂｊｅｃｔｍａｎａｇｅｍｅｎｔｓｙｓｔｅｍ）的操纵语言和所有集成工具的编程语言，同时也是支持最终用户的通用的编程语言．本文首先简要介绍了ＣＡＳＥＣ＋＋的设计背景．然后，较详细地讨论了ＣＡＳＥＣ＋＋中新引入的语言成份：永久对象；类定义的共享机制；永久对象间的关系描述──链和对象的内容等．最后，给出了实现方法．

[Abstract]
CASE C+ + is an object oriented programming language of fully compatible with C+ + and supporting persistent object, which is originally designed and implemented in the object oriented CASE environment Jade Bird 2 System. In Jade Bird 2,it is the manipulation language of OMS (object management system) and the programming language of integrated tools. At the sametime, it is also the end users' programming language. The paper briefly introduces the background of designing CASE C+ + at first.Then it focuses the discussion on the new added language components in CASE C+ +,such as persistent object; share of the class definition;link declaration and content of object. At last, the method of implementation is described.
