With CAI in its infancy and in a necessarily experimental stage, there is little available data upon which to develop quantitative support for the opinions expressed herein. In this respect, CAI bears a definite kinship with \"time-sharing\" systems. It can in fact be strongly argued that CAI is essentially a special form of the \"time-sharing\" system. At this stage of CAI development we are still dealing with \"guesstimates\" of mass storage requirements for course material, quantity of course material required to reside \"on-line\" at a given time and tolerable response times in the interaction among student, student terminal, and terminal controllers.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126574538","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}

Control concepts for continuous processes use the computing, monitoring, information storage and analytical ability of the direct digital control computer. In the batch or discontinuous process the computer's logic capability is emphasized. To perform batching operations, a comprehensive logic system is necessary. Implementation of such a system using digital techniques provides many advantages over implementation using analog equipment with auxiliary digital logic circuits.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115886168","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 uncommon characteristics include a strong affinity for redesign; a framework for debugging that eliminates the need for memory dumps, symbolic snapshots, and other conventional debugging aids; and an adaptability to machines of various memory sizes and configurations without reprogramming.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122063703","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}

Although designing and writing a compiler for a special purpose language is no more a mysterious task as it was ten years ago, it is still, in most cases, a very tedious task that might take a large number of man-months to perform. The purpose of designing a generalized table-driven compiler system is to allow a user to write his own compiler for his special language at a reduction of the time currently required in the implementation of a compiler for a new source language. It should be pointed out that not only can a user design a compiler of his own but he can also make modifications, large or slight, to an existing compiler developed with the system. This, therefore, also provides an ideal simulation environment in connection with the implementation of new ideas in translation process. This particular line of development in translation systems naturally lends itself to the increasing use of digital computers in a time-sharing environment.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129858843","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 former can be considered to have come of age: there are over twenty-five brands of off-the-shelf consoles with all the requisite input devices, and new techniques and improvements are constantly being developed. Many consoles are also provided with primitive supporting software which allow one to draw points, lines, arcs, etc., in a symbolic language of some sort. Less well understood and developed, however, is that aspect of display software concerned with representing and manipulating the problem model from which these primitive point/line/arc pictures are derived. The \"data structure\" is the machine representation of the often complex and hierarchical problem model. It must be judiciously derived from the model on the one hand and, on the other, lead readily to the reduced console display file of points, lines and arcs which cause the actual visual display. Furthermore, the data structure must be efficiently stored and processed (usually contradictory requirements).","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130565503","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}

Machines are assembled by plugging the modules into cells of a special frame which provides for communication between adjacent cells. Explicit data pathways and control structures are then made by plugging in standardized cables. All pieces of a system are therefore recoverable and systems can be reconfigured easily. Data modules process twelve-bit word-segments; greater word lengths are obtained by interconnecting modules. Memory modules hold 4096 twelve-bit segments and can also be interconnected to form larger arrays. Particular attention is given to the problem of designing control structures. The control signals for a given process are routed along the cables of a control network whose topology is isomorphic to the flow diagram representing the process. The step from conception to realization can therefore be made directly.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122592688","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}
