Abstraction techniques, such as abstract data types, can support both the specification of display interfaces and the implementation of those interfaces in a variety of styles. These abstraction techniques also guide the organization of software systems that will use display interfaces. We are developing a system that includes specifications, interface description tools, prototype organizations, and runtime support. The emphasis is on flexibility and on the separation of policy from particular instances. Preliminary results from implementations in a prototype domain indicate the feasibility of the approach.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131559179","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}

Computer science provides an abundance of tools, including specification languages, design languages, special-purpose programming languages, and even wide spectrum languages, capable of accommodating the goals of all the preceding languages in a single, unified package. Unfortunately, as computer scientists become more involved with the software development process, the role of the end user tends to diminish. Throwing languages at a problem domain, either in greater numbers or in great flexibility, does not necessarily properly address the needs of the party who wanted the software in the first place. The problem is that, however noble the intentions of language designers may be, the end user will ultimately confront situations in which the major obstacle is one of mastery of the language, rather than difficulties in the problem domain. As an alternative, we propose that more attention be paid to the environmentin which software development takes place than to the languagesin which the stages of development are expressed. This talk will discuss environmental facilities which enhance a user's syntactic and semantic understanding of his software tools.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114452853","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}

This paper shows that when using a strongly typed programming language, that language should support the notion of type hierarchies to achieve a full integration of Semantic Data Models abstraction mechanisms within the language's type system.

They also increasingly recognize that maintenance costs tend to overshadow development costs. These two factors even multiply their adverse effects: as the user needs evolve, it is the interface with a system which generally requires the most maintenance. The user relationship is even said to account for about 60 percent of the maintenance problem [Lientz and Swanson 81].\u0000 Surprisingly, few programming language constructs are designed to address the area of user interface design. On the contrary, traditional programming language constructs are strongly oriented towards improving programmers' effectiveness in developing the algorithmic and data manipulation aspects of an application.

These rules permit a programmer to specify explicitly the duration and visibility of all objects. Such specification can be used to declare variables or to create data structures which persist from one invocation of a block to the next. In addition, the data may be caused to persist from one run of the program to the next, obviating temporary files which are outside the scope and control of the programming language. The visibility of an object may also be specified to be larger than the block that contains its declaration. This facility allows the programmer to export some objects, yet keep others private. Finally, a facility for call-site visibility is presented that provides some of the expressive power of dynamic scoping and macros without their inherent type insecurity.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130585775","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}

A C language derivative is used for more complex program combinations involving looping or branching. This paper presents an alternative shell language based on natural extensions of the pipe concept.\u0000 “Structured data streams” are introduced as a means of expressing potentially concurrent processing, and “labelled data streams” serve to route data to one of a pool of programs. These complex data streams are hooked together with functional operators much as simple data streams are hooked together with pipes. A generalized notion of “powers” provides for repetition of programs and also for systems that take an arbitrary number of input streams. This provides a uniform way of building complex tools from simple ones, as advocated by Kernighan and Plauger [8]. A major advantage of this new shell language is its program algebra, which facilitates system verification and analysis.","PeriodicalId":414056,"journal":{"name":"SIGPLAN Conferences and Workshops","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130307655","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}
