Modern object oriented languages like Java [1, 3] and Python [2, 6] use reference counting to free the programmer from the concern of object allocation and deallocation, thus making possible memory leaks almost obsolete. The reference counting pattern outlined here is being used with the PyF95++ pre-processor [5] and the accompanying Standard Template Library. All the containers in that project are reference counted containers and employ this pattern. The result of this pattern is something akin to an auto ptr template class in C++ [4].","PeriodicalId":379614,"journal":{"name":"ACM SIGPLAN Fortran Forum","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126890044","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}

Recent comparisons of Fortran with C++ have cited the lack of templating in Fortran as a major deficiency in the language [1]. Templating is a very powerful capability which allows the programmer to easily create and maintain more complex code than would be desirable to do manually. There are some very good C++ resources on templating for those not familiar with the subject [4] and are worth reading to gain a more thorough appreciation for the concept than what will be discussed here.","PeriodicalId":379614,"journal":{"name":"ACM SIGPLAN Fortran Forum","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126272059","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 is particularly true for the programming languages C and Fortran. The use of the alternate language often results in efficient running time or the effective use of human or other resources.\u0000 Prior to the Fortran 2003 standard there was silence about how the two languages interoperated. Before this release there existed a set of differing ad hoc methods for making the inter-language calls. These typically depended on the Fortran and C compilers. The newer Fortran standard provides an intrinsic module, iso_c_binding, that permits the languages to interoperate. There remain restrictions regarding interoperable data types.\u0000 This paper illustrates several programs that contain core exercises likely to be encountered by programmers. The source code is available from the first author's web site. Included is an illustration of a \"trap\" based on use of the ad hoc methods: A call from a C to a Fortran 2003 routine that passes a character in C to a character variable in Fortran results in a run-time error.","PeriodicalId":379614,"journal":{"name":"ACM SIGPLAN Fortran Forum","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126572401","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 was a second substantial reduction of the scope of the work for Fortran 2008.
