I am a beginner about fluka, when I study the example of source.f file, I can not understand the “call” program.In fortran77 its function is to call subroutines, but in the example the subroutines is not defined anywhere in these example. Is it a flkua built-in subroutine？
Thank you for your reply. If I want to know the details of these built-in subroutines (such as how to use them and their functions), where can I check them? I can’t find the relevant instructions in the user manual.
Thanks for your reply, could you please help me explain the following subroutines：
When I learned to write .f documents, I found that these subroutines often appear. If you can help me understand them, my learning will be easier，I want to know their parameters and functions，I would appreciate it if you could teach me.
