GUI development with Fortran - The usual bashing point for FORTRAN is that it doesn’t have any GUI building capabilities. Its not designed to be. It was developed in the days of punch card and ever since speed, portability and backward compatibility has been its pillars of success. But this doesn’t mean, we can do GUI with FORTRAN. Here’s the […]
What to use? F90 or F for Fortran programs - There’s a lot of confusion on using F90 and F extensions for FORTRAN program.

  1. I have read with interest Sukhbinder’s comments about GUIs and Fortran applications.
    I have gone down the DISLIN route. Here are some screenshots of the GUI for a structural engineering application I’ve recently completed using GFortran to analyse skeletal framed structures:

    http://alturl.com/h9x2g

    The screenshots show the program in its not-fully-debugged state, so there are errors in the output results which don’t appear in the completed version. The GUI is nevertheless fully demonstrated by the screenshots.

    Anyone interested in more information, feel free to contact me: John@Wasilewski.co.uk
