Abstract. This paper presents an overview of an integrated graphic environment
called P­GEN (1) to develop applications based on attribute grammars. The
system has a modular structure to enable integration of different modules for all
phases of the processing of an attribute grammar specification. This environment
contains routines for transforming attribute grammar specifications written in
different formalisms to an internal representation. The system assists the
interpretation of the most important evaluation strategies. The graphic
representation of the parse trees and attributed dependency graphs is also
supported.
1 Introduction
Attribute grammars [Knu68] are probably the most adequate of the tools available
