Hey, i’m having problems to compile this code, i don’t really know the right commands to compile properly, the way i usually do it is “gfortran -o code.f90”. I think this code is quite old so new features were added but i don’t really know how to “translate” it to modern versions. If someone could help me on that, it would help me a lot.

What steps are you taking to compile the file?  
Also, you don’t really have to convert to Modern Fortran to get this to compile.

I was able to compile the program successfully with the following steps:

- rename: `parC.txt` → `ParC.inc`
- rename: `CouetteAI.txt` → `CouetteAI.F`
- `gfortran CouetteAI.F` compiles the files

Yes that is correct. You will notice however that, that is a Warning, not an Error.
