In the first, I discussed revision control (rcs), compilation control (make), and checking procedure interfaces and common blocks. The idea is to give an older, Fortran 77 (or earlier) code a check-up before trying to modify it. I also discussed automatic conversion of older Fixed Format source files to the modern Free Format. Free Format is easier to use, and can eliminate some problems present when using Fixed Format, mainly associated with searching for names. In this article, I'll discuss the Fortran kind mechanism for selecting types and the Fortran module for sharing data among procedures. Next, I'll try to tie the notions of agreement in type, kind, and rank, the use of procedure interfaces and common block consistency issues together with the use of modules.","PeriodicalId":379614,"journal":{"name":"ACM SIGPLAN Fortran Forum","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127550780","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}

{"title":"Comments on the Arjen Markus article: Design patterns and Fortran","authors":"H. Gardner, V. Decyk","doi":"10.1145/1148105.1148107","DOIUrl":"https://doi.org/10.1145/1148105.1148107","url":null,"abstract":"The article by Markus [1] discusses the subject of object-oriented (OO) design patterns and describes ways in which three well-known patterns might be implemented in Fortran 90/95. It appears that the idea of object-oriented design patterns in Fortran might just be coming of age and it is a very appropriate subject for discussion in a Forum such as this.We have been developing our own implementations of design patterns in Fortran 90/95 for some time and have one paper under review [2] and another being presented at the 6th Workshop on Parallel/High-Performance Object Oriented Scientific Computing (POOSC) in Nantes, France in July 2006 [3]. Our application area is particle-in-cell simulations in plasma physics, but the results that we have obtained will, we hope, be of interest to Fortran 90/95 programmers in general.Our own starting point with design patterns in Fortran 90/95 stems from the literature on object-based programming in that language [4-10]. Several authors have observed that the obvious unit of encapsulation, the Fortran 90/95 module, can be thought of as an object-based class: it can support a type which defines the stored data together with subprograms which can operate on that data. With some discipline and ingenuity, these authors have shown how to emulate the notions of object construction and destruction, inheritance and polymorphism. These emulations were actually implemented using object composition. For example, one child module might include another parent module in order to simulate inheritance. As Markus correctly points out, most of the famous design patterns are based on object composition and the authors of [4-10] have, frequently, been using design patterns as a way of simulating OO behaviour.Because the subject of OO design patterns in Fortran 90/95 is so fresh, there is ample scope for them to be presented in different ways by different authors. Whilst appreciating the clarity and relevance of Markus' expositions, we would like to make some points of criticism which we believe are important to a further discussion of this topic. The points we make refer to the ideas expressed in the book by Gamma et al. [11] which is considered to be the fundamental exposition of the topic of OO design patterns.","PeriodicalId":379614,"journal":{"name":"ACM SIGPLAN Fortran Forum","volume":"50 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134543911","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}

Reid","doi":"10.1145/1148105.1148108","DOIUrl":"https://doi.org/10.1145/1148105.1148108","url":null,"abstract":"Two important meetings for the next revision of Fortran were held recently. WG5 met jointly with J3 in Fairfax, Virginia, Feb. 13-17 and J3 met in Las Vegas, May 8-12.The framework was decided at last years' WG5 meeting and was not substantially changed at this year's WG5 meeting. Two large items (bits and intelligent macros) were left as do if time, which made the May J3 meeting important, since the schedule that we have adopted (aiming for the revision to be Fortran 2008) demanded that edits against Fortran 2003 for all the new features be completed at that meeting.In the event both were deemed to be ready, but interoperability of pointers, allocatables, assumed-shape arrays, and optional arguments was not ready and will be deferred to a Technical Report.There was a discussion at the J3 meeting over moving co-arrays to a Technical Report or another part of the standard, despite the WG5 decision at the February meeting that it be a first priority item. However, the major vendors reported pressure from users to provide co-arrays and it was decided (straw vote 6-3-2) to keep them. A significant argument was that it would be unsatisfactory to renege on the decision of last year that co-arrays would be there.This seems a good moment to give a quick summary of the new features.

{"title":"Interoperability with C in Fortran 2003","authors":"A. Donev","doi":"10.1145/1124708.1124710","DOIUrl":"https://doi.org/10.1145/1124708.1124710","url":null,"abstract":"One of the major new features in the Fortran 2003 is features for interoperability with C © Interop). The intrinsic module ISO_C_BINDING provides:• constants, mostly type parameters, C_NULL_CHAR, C_NULL_PTR, and others,• types, and in particular, TYPE(C_PTR) and TYPE(C_FUNPTR),• procedures, such as C_LOC, C_FUNLOC, C_F_POINTER, C_F_PROCPOINTER and C_ASSOCIATED.A Fortran interface can be specified for a C function with external linkage and used to invoke such a function. The interface has the characteristic BIND(C) label, and must also satisfy some additional restrictions.C Interop can be used to portably use multi-language codes in Fortran. Since most languages interoperate with C, the feature can actually be used to interoperate with other programming languages as well. C Interop can also be used to give access to Fortran programmers to the many standard libraries with widely-used and implemented C interfaces. This includes lower-level tasks such as interfacing with the OS on UNIX-based systems, or using special libraries like OpenGL.For simple API's, developing Fortran interfaces is practically trivial once one gets some experience. For more complicated API's whose full functionality/power is not needed, such as for example TCP/IP sockets or shared-memory segments on UNIX systems, it is often easier to develop a condensed C API/library that does the actual work, and is simpler to interface to from Fortran. However, for libraries like OpenGL, one should provide a full Fortran interface so that the whole API can be accessed. Doing this manually is not easy and is also error-prone due to the size of the OpenGL/GLU/GLUT interfaces. For certain libraries like MPI, a special Fortran interface may be defined for the purposes of efficiency, portability, ease-of-use, or to accommodate for language semantic differences.In this first paper, we will show how to develop a Fortran interface for a simple C API/library. In a second paper, we consider automating the process so that large and more complex API's, and in particular, OpenGL, can be handled. The source codes can be obtained at http://atom.princeton.edu/donev/F2x.Along the way, we identify some problems with the design of C Interop in Fortran 2003.","PeriodicalId":379614,"journal":{"name":"ACM SIGPLAN Fortran Forum","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130097482","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}
