It is therefore necessary that Ada be precisely understood by both its users and implementers, in order to ensure the quality of systems written in Ada. In particular, since DoD must control Ada compiler implementations, a precise, well-structured, and validated formal definition of Ada can provide one of the principal standards to which these implementations must adhere. Beyond such considerations pertaining to particular programming languages such as Ada, good generic research toward the design and implementation of tools and methodologies for supporting the development of precise, readable, and accurate formal definitions has considerable relevance to the broader goals of understanding large programs and verifying their correctness.","PeriodicalId":304626,"journal":{"name":"Proceedings of the AdaTEC Conference on Ada","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124148338","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}

July 1980 Ada [Ada-80] further requires that this order be chosen so that no formal access-before-elaboration (F-ABE) situation result. The proposed revisions to Ada following the ANSI canvass [Ada-82] have eliminated this requirement but now provide that an actual access-before-elaboration (A-ABE) shall cause the exception SOME_ERROR to be raised. This paper will define F-ABE and A-ABE, will discuss rationales for both the old and the new rules, and will discuss implications of the new rules in relation to other language features proposed for inclusion in 1982 Ada. The algorithms used in IAPC-20, the Intermetrics Ada Prototype Compiler for TOPS-20, which implement the July 1980 rules regarding F-ABE and OOE, will also be discussed and sketched.","PeriodicalId":304626,"journal":{"name":"Proceedings of the AdaTEC Conference on Ada","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1982-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122118504","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}
