Two-level graph grammars,oduced by v. WIJNGAARDEN for the formal definition of ALGOL 68. 2GG‘s settle both the inadequacies of one-level graph grammars and of two-level string grammars, the former resulting from the lack of parameters, the latter from the general lack of structure of string manipulation systems.

Graph grammars and operational semantics,theory of graph grammars (cf./Eh 78/) and the ADJ approach to semantics of programming languages it will be proved that the correctness of transformation rules carries over to the correctness of derivations via such rules. Applying this result to LISP we show that a LISP interpreter represented by aExhilarate 发表于 2025-3-26 19:03:59
