Hello, I'm a student, and I downloaded the free license of Intel® Parallel Studio XE 2017. To perform labouring in Fortran. But the problem is that the standard of 77 years is needed to carry out laboratory work. Therefore, the following question arose: can I switch it somehow (I use Microsoft Visual Studio 2015)? If yes, you were grateful if you provide step-by-step instructions on how to do this.
Yours faithfully, Vasily.
There is no need to switch anything. Intel Fortran fully supports FORTRAN 77 source code. That's one of the great things about Fortran is that it is "upward compatible with few exceptions, even going back to FORTRAN IV. Just make sure, if you are entering source code that worked in F77, that you do so using a source file name with a file type of .f or ,for and not .f90.
Whoever told you that you specifically needed a F77 compiler was mistaken.
