| Abstract: |
| This paper developed XYZ/NGAE system based on AG(attributed grammar)．The system generates the FEC(front—end compiler)of a programming lan-guage automatically．In this paper，AG and the language for attribute definition are intro-duced at first．then the system structure of XYZ/NGAE and the attribute optimization technique are described． |
| Key words: Attributed grammar,front—end compiler,attribute space optimization． |
