Well, my larger goal is to be able to call a Fortran function from C#.
It's not important to me to use native DLLs or any other specific approach.
Can you suggest an approach which can lead toward the goal?
I have been reading about p/invoke but I haven't been able to devise
a solution based on that; if you have any hints that would be great.

Thanks for your help,
