From: Terence on 8 May 2010 21:57 Interesting to see the arguments presented; especially some of the comments about whan and why some contributers switched from F77 (or even Fortran IV). I think that a new entrant to Fortran SHOULD learn the latest language, but first consider using an F77 programmer's guide as an introduction to Fortran-whatever, in order to get the underlying concepts across, but be pre-warned about the free form and lower case text options that are to come. I never found that fixed-form needed any care with columns once you knew to start in 7 and allow the insignificant-blank concept to braek any long lines up between operators (using 6 when necessary). When the student has got these concepts and tried some F77-style problem coding with success, then he an start to read one of the much more recent guides. They REALLY are complex in my opinion. I'vee read two, many many times and it hasn't really all sunk in, eevn if I've written many F95 complex programs. As others have pointed out, an F95 or F2003 "guide" can be overwhelming in complexity. I remember that when we had at least 16k bytes of memory, then Fortran startered to be really useful, especilly if you could get onto an IBM1401 or 1620 box. I think I was lucky to get the use of both of these and also a 7040 in 1961. I still prefer coding with F77, because, if done with two simple GUI libraries, you can choose to compile and run in DOS, or Windows or evn Mac Windows-emulating computers. The resulting compiled F77 code is about one fifteenth the sie of an identical Windows mode compilation of the same source (diffeent libraries). I don't think you ever lose the concept of not wasting storage of memory space when you start life so resource-limited.

This *is* still on-line but I have had serious doubts as to whether anything on Fortran77 ought still to be made available. As others have said, you should be using Fortran95 - which includes practically the whole of Fortran77 as a subset, but is simply easier to use and much more powerful when you need the power. A comprehensive tutorial on Fortran90/95 can be downloaded from: http://www.liv.ac.uk/HPC/HTMLFrontPageF90.html There are many links to other tutorials and useful documents here: http://www.ifremer.fr/ditigo/molagnon/fortran90/engfaq.html -- Clive Page

Other compilers for Fortran 95 without this problem?

Yes, it's the free version of a product that they want you to buy - what do you expect? For an open source compiler, i.e. not a commercial package, try: g95 www.g95.org or gfortran http://gcc.gnu.org/wiki/GFortranBinaries -- Clive Page

If you are learning it on your own F90/95 can be bewildering. I certainly don't suggest sticking to F77, though. Just use it to get started. |
