Make a function and then run it with different values.

Have a look at the attachment.  Doesn't create a /function/ in the
Fortran sense but shows how you can definitely call some code with
different values.

That's about all I can help with as it's been years since I used Fortran
(although I did cut my teeth on Fortran 66... ;-)).

Thank you so very much, I will check it out.

Is there anyone in particular who would know some more things about fortran
in org-babel?

Fortran is listed as supported on
https://orgmode.org/worg/org-contrib/babel/languages/index.html
so I would hope that the standard tipps there apply.

Re: orgbabel with fortran code

The code is fantastic, but how may I run it exactly?  Using "C-c C-c"
tells me "'C-c C-c' can do nothing useful here".

You may need to evaluate (require 'ob-fortran) in your init files.

Have you got exomples with fortran code yourself?  I would like to scrutinise them.

I have this, but I no longer know whether it actually executes fortran
inline or only tangles it:

I can tell you that I used Fortran for much of my secret underwater surveillance
work.  Richard Stallman doesn't like it and we butt heads.  But you should know
that I come from area known as Afro-Asia.  I always win.

Have seen yon also use ob-latex.  Have tried to display equations but was not
successful.  I would be grateful with some help on that Arne.

Where did you try to use ob-latex? I mainly use latex-export (and quite a
large amount of it).

Re: orgbabel with fortran code

[pietru]

Have had a first go with your code

I wrote the following, then went inside the code and slammed "C-c C-c" 

#+BEGIN_SRC fortran :tangle fortran-comline.f90
program cli
  implicit none ! no implicit declaration: all variables must be declared
  character(1000) :: arg
  
  call get_command_argument(1, arg) ! result is stored in arg, see 
  ! https://gcc.gnu.org/onlinedocs/gfortran/GET_005fCOMMAND_005fARGUMENT.html
  
  if (len_trim(arg) == 0) then ! no argument given
      write (*,*) "Call me --world!"
  else
      if (trim(arg) == "--world") then
          call get_command_argument(2, arg)
          if (len_trim(arg) == 0) then
              arg = "again!"
          end if
          write (*,*) "Hello ", trim(arg)
          ! trim reduces the fixed-size array to non-blank letters
      end if
  end if
end program
#+END_SRC

And then I wrote this, went inside the code and slammed "C-c C-c" 

#+BEGIN_SRC sh :results output :exports both
  gfortran -std=gnu -O3 fortran-comline.f90 -o fortran-comline
  ./fortran-comline
  ./fortran-comline --world World
  ./fortran-comline --world
#+END_SRC

But I am getting some major whining

/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'

It is supposed to work, so tried to crack it.  Could be useful an attempts 
could drive some improvements.

Re: orgbabel with fortran code

[pietru]

Perhaps we can have a crack at ob-fortran again, considering you have had
some successes.  With the motivation that this could drive some more work 
on the code if useful.  Would some hacking time of a few days bo possible 
to you?  We can then compile a brief report and send it.  

Thank you so very much Arne.
