When I code Fortran, and use tabs for indentation, Vim highlights those spaces in red, because in older Fortran the first 6 columns were special and reserved for labels/line numbers and continuation symbols. How can I make Vim stop doing that?
Thank you.
Actually, tab is not part of the Fortran character set, and portable code should avoid it. So instead I’d recommend to configure vim to use spaces instead of tabs for indentation, see the “expandtab” option.
