At MIT we came prepared to agree on what problems remain to be solved, but we did not bring complete solutions.","PeriodicalId":262740,"journal":{"name":"ACM SIGPLAN Lisp Pointers","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125252153","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}

For a succinct summery of these see Padget and Fitch [1985], which includes a proposed third model. It is often claimed that shallow binding are unsuited to systems which allow context switching. We wish to describe an alternative binding model, deep binding with cacheing, which provides the efficiency of shallow binding in \"ordinary\" call/return control, while exhibiting the ease of context switching of deep binding. This binding model was implemented in the Lisp system built at the IBM Research Center, later elaborated into LISP/VM. In this article the term LISP/VM will be used to encompass both that program and all of its progenitors developed at IBM Research.","PeriodicalId":262740,"journal":{"name":"ACM SIGPLAN Lisp Pointers","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116043813","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}

In the approach presented here, stepping is achieved by annotating the user's program with calls to stepping procedures. This provides greater flexibility in the selection of which program sections the user is interested in stepping. In addition, the sections not selected are executed without overhead. Stepped program sections are visually highlighted inside the user's program editor, providing a sense of context. Stepping control mechanisms, such as the ability to execute until a certain point and then step, permit the user to navigate through a program in a precise and flexible manner. A prototype stepper based on this approach has been implemented.","PeriodicalId":262740,"journal":{"name":"ACM SIGPLAN Lisp Pointers","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116987679","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}

The original title was a weak pun on the technical term environment. An environment, you see, associates names with their meanings. In the Scheme environment, for example, the word \"environment\" has the meaning just stated, while in some other parts of the programming language world the word \"environment\" has a less technical meaning that refers to the stuff that comes with a programming system. One of my purposes has been to explain the meaning of terms in the Scheme environment. Sometimes a word like \"environment\" or \"stream\" means something different in Scheme than it does in some other dialect of Lisp, usually because the Scheme terminology follows that of another well-established language or group of languages.","PeriodicalId":262740,"journal":{"name":"ACM SIGPLAN Lisp Pointers","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132583501","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}

The first section briefly describes garbage collection. The next section gives a general description of what has come to be known as the \"classical\" garbage collection algorithms. A few of the classical algorithms' shortcomings for use in today's systems are described in the next section. This is followed by a section on a few techniques in garbage collection which address the needs of today's and tomorrow's symbolic computing systems.","PeriodicalId":262740,"journal":{"name":"ACM SIGPLAN Lisp Pointers","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134194770","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}
