Within two and one-half years, eight high schools had tied into the Dartmouth System. The effects were startling. Hundreds of students were taught the BASIC language. Some of them produced highly sophisticated programs. Teachers were using computer applications in mathematics and science courses. These effects convinced Dartmouth of the high value of computing in secondary education. However, the results were not sufficiently examined. There was no documentation on recommended procedures nor written units of classroom applications. Therefore, in the spring of 1967, Dartmouth College proposed that the National Science Foundation support work in developing, expanding, sharing, documenting, and publishing the results of computing experience in secondary schools.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116431643","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}

Furthermore, as the amount and complexity of the available information has continued to grow, the use of mechanized or partly mechanized procedures for various information storage and retrieval tasks has also become more widespread. While a number of retrieval systems are already in operation in which the search operations needed to compare the incoming information requests with the stored items are performed automatically, no systematic study has ever been made of the use of man-machine interaction as a part of a mechanized text analysis and information processing system. Specifically, the recent development of high capacity random-access storage mechanisms and conversational input-output consoles should permit a rapid interchange of information between users and system. Such an interchange can then be used to produce improved search formulations, resulting in a more effective retrieval service.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114920496","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}

While such a statement no longer raises eyebrows, in few other cases has the extent of the infusion of computing into the life of the university community been as great, or as painless, as at Dartmouth. The purpose of this paper is to report some of the many ways in which computing has been found useful in teaching and research at Dartmouth, and to claim that these almost revolutionary (though almost painless) developments were generated primarily by having freely available to all students and faculty a general purpose time-sharing system equipped with a simple and easy to learn language (BASIC), and a simple and friendly user interface.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116652111","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}

Wilkes","doi":"10.1145/1476793.1476836","DOIUrl":"https://doi.org/10.1145/1476793.1476836","url":null,"abstract":"In a time-sharing system that is intended to serve a number of console users simultaneously, there are two related, but distinct, functions to be performed. One is time slicing, which is the allocation of bursts of processor time to the various active programs according to a suitable algorithm. The other is core space allocation which arises because, in a modern multi-programmed system, there will be space in core for more than one active program at the same time. If, as will normally be the case, there are more active programs than can be accommodated in core, some of them must be held on a drum and brought into core periodically; this is swapping. Confusion has sometimes arisen between time slicing and swapping, since, in the early time-sharing systems, there was only one active object program resident in core at any time, all the others being on the drum. In these circumstances, swapping and time slicing go together; when a program is in core, it is receiving processor time, and as soon as it ceases to receive processor time it is removed from core. In a multi-programmed system, however, space allocation and time slicing can proceed independently. It is the responsibility of the space allocation algorithm to ensure that, as far as possible, there is always at least one program in core that is ready to run. The time-slicing algorithm is responsible for dividing up the available processor time between the various programs that are in core.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131422593","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}

Because of the need for precision in the specification of complex systems, BNF has been used to record the syntax of many other programming languages. The rules of BNF are equivalent to context-free production rules. However, due to its declarations, ALGOL is context-dependent, and its syntax cannot be fully specified by a grammar limited to context-free rules. Other grammars for ALGOL are more compact than the BNF of the defining report, but they are generatively no more powerful. Because of this context-dependency of declarations, even an assembly language cannot be fully specified in BNF.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129975548","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}
