In our current activities concerning LISP, we are trying to characterise pure LISP as an ALGOL-like programming language in the sense of ALGOL 60 resp. ALGOL 68 /1/, /2/. LISP is considered as a sublanguage of ALGOL 60, where the datatype \"s-expression\" with its 5 standard functions is introduced and where procedure identifiers are allowed as values of function-procedures (ALGOL 68) in order to have upward FUNARGs /3/. In contrast to the operational semantic definitions via interpreters, this approach gives a precise, mathematical definition of the LISP-semantic. Within this framework we are able to prove properties of LISP-programs much easier than using inductive proofs based on an interpreter. Our method for modelling variable bindings follows the well known ALGOL 60 definitions, which are very close to the FUNARG-feature of LISP 1.5, while other authors prefer the \"shallow access binding\" method; e. g. M.J. Gordon gives a formal definition of pure LISP by algebraic methods /4/.","PeriodicalId":404213,"journal":{"name":"ACM Lisp Bulletin","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129058622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These problems are :\u0000 1) The exhaustive description of the implementation. We propose a description based on the virtual, referential and prototype machine VCMC2.\u0000 2) The adequate representations of the VLISP objects and functions. We have associated some natural properties and we have established a functionnal typology.\u0000 3) The efficiency of the interpreter (in words of core, execution time and power). Our iterpreter does, for his own need, a optimal core allocation (in term of CONS module calls). The direct acces (which needs only one memory access) to the values of objects variable and function, and a type classification of functions allow a direct invocation of all typed functions.\u0000 4) The power of control structures. Our implementation's KIT generalizes the VLISP control structures SELF an ESCAPE, extends them with the new constructions EXIT, WHERE and LETF and unifies completly their description and implementation.\u0000 An incarnation of our model is given by the realization of a complete VLISP system in the referential machine VCMC2.

In order to understand the program, the system meta-evaluates it, using a library of \"pragmatic rules\", describing the construction and correction of general program constructs, and a set of \"specialists\", describing the syntax and semantics of the standard LISP functions. The system can use its understanding of the program to detect errors in it, to debug them and, eventually, to justify its proposed modification.
