Which command would you use to run a Fortran code?

Fortran is a programming language, which means you write a program in Fortran, and COMPILE it to an EXECUTABLE program. The compiler you use differs depending on which operating system platform you intend to run the program on. If you wish to run the program on a PC using Windows XP, you must first compile it using a specific Fortran-compiler for Windows XP.

The result after compiling will be an executable file (with the file-ending . Exe). To find a suitable compiler, check out download.Com, for instance Given that you know it is Fortran Code, we can assume that you do not have a compiled one, but just raw Frotran Source code To compile it, you need a Fortan compiler suitable for both your operating system as well as the version of Fortran the code was written for There is a free Fortran Compiler for Fortran77 from the GNU Project: For Windows: http://www.geocities.com/Athens/Olympus/5564 For Unix: http://www.gnu.org/software/fortran/fortran.HTML The above is correct assuming your question is "Given the Fortran source code, how do I run it?

" However if your question is "Given the Fortran executable (ProgName. Exe) how do I run it?", the answer is that you run it like any other program. You either: 1 - Double-click on the file name OR 2 - Open a DOS window, go to the directory where the file is and type in the filename with or without the extension .

Exe OR 3 - You can select Start and Run and type in the filename Like any "compilable" language it can be used to build an exe or a dll. But a dll MUST be called by another program to run, you can only run a . Exe directly In addition the workflow for running a Fortran program on a *nix platform (such as Unix, Linux, or Mac OSx) would be as such: 1) Write given Fortran code with proper extension a) Fortran 77 - *.

F b) Fortran 90 - *. F90 c) Fortran 95 - *. F95 2) Compile using your compiler suite (showing examples for a few different cases) a) for gfortran as mentioned above gfortran myfile.

F90 -o myExecutable g77 myfile. F77 -o myExecutable b) for OpenMPI mpif90 myfile. F90 -o myExecutable mpif77 myfile.

F77 -o myExecutable c) for Intel Fortran ifort myfile. F90 -o myExecutable 3) To run the executable first make sure it is marked as executable, this can by going to the folder in which it was compiled then typing: ls -l.

The convenience of its users, but is not part of GNU Fortran. Needed by Fortran programs while they are running. Functions this way.

Having any component compiled by GNU Fortran. The f771 program represents most of what is unique to GNU Fortran. Large chunks of code.

Which knows how to generate fast code for a wide variety of processors. Cc1plus, and f771, plus others. Whenever the distinction is important.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
