A language for acyclic groups

Abstract We present a language for acyclic chemical groups, which has a context-free grammar, and which is close to current chemical denotations. An interpreter which accepts the language, produces a connection table, and performs valency checks has been written in PASCAL. The source code and executable program are included on disk.
