So, I was trying to run my rtf file in Brew to compile it, but that didn’t work. So I went and tried to use Vim, but I don’t really know how to use it. I looked online, but nothing helped. So I looked for the best place to convert my file. Though I couldn’t find one. Please tell me! Also a guide to Vim would help too!

When I used Vim to edit the file, I couldn’t click, add, or delete text? Im new to Fortran, and Vim please tell me if I did something wrong and how to fix it!
