USSA—universal syntax and semantics analyzer
Boris Burshteyn · ACM SIGPLAN Notices · 1992
This article presents a new tool for defining syntax and semantics of formal systems, called USSA ( Universal Syntax and Semantics Analyzer ). USSA is based on modifiable grammars introduced in [1, 2]. While parsing or generating the source text, USSA applies context-free rules from the current set of rules and modifies this set on the fly. The USSA concepts are illustrated by a rich variety of syntax and semantic constructions from programming languages.
