Fortran 77 code not running in VS code

[Mayank140889]

Hello,
I am working on one of the old project which was written in old Fortran 77 language syntax fashion with extension filename.for . I want to run the code in VS code and it give me error of "code language is not supported or define". I selected language as Fortran 77 but still code is not running. I also installed modern Fortran extension but the problem is same. kindly Help me to fix the problem @gnikit
