    how to write fortran program in windows

    If your Fortran environment has been successfully installed, you should run your own programs. Just follow these steps:

    1. Start Regime-Geany by clicking the marker on the desktop or in the Windows Start menu.
    2. For now, click the Open File icon in the geany action bar (see photo). This will open a track dialog where you can select a Fortran file to open. If you didn’t download our software database at all in Chapter 1, now is the time to do so. Select the repository prog01_01.f90 in the program and open the database.

    3. Once the file gets large, multiple icons end up with the geany taskbar being activated. We, the three most important symbols, are marked in red in the following image.

      From left to right, use the Compile , Build Execute buttons and your own code. To organize the program prog01_01.You f90 , you must press each of these buttons one after the other. In properties they will do the following:

      • Compile interprets the source code of a service in a binary, knowing that GNU gfortran is named prog01_01.o .
      • In the next step, the Build button builds all the relevant binaries (of which there may be several if there are modules) and associates these elements with the executable for which it is specific to the runtime.
      • Finally, the Execute button launches the exe file created in the current step.
    4. If the program was compiled and built successfully, a console window should appear showing the output of the entire program, in our case the introduction of 'Hello World' .
