I thought offhand that cards went out before F77 came in. But maybe
the book authors hadn't kept up. I last used cards with F63.
Short summary: a Fortran source file is a text file, and can be prepared
on your "interactive or real-time" computer using the text editor of
your choice, saved as a disk file, and then submitted to the compiler.
If you wish, you can count out the columns as specified in the book.
Col <1-5> Statement Number (if any)
Col 6 Continuation mark (if any)
Col <7-71> Source Text
Col <73-80> reserved for card sequence number
All the implementations of Fortran that I have seen for computers
that have serial terminals, text editors, etc. rather than card readers
have a more free-form input style:

I was still using cards on the IBM 4331 in 1980 and then when I moved
to the UNIVAC 1100 we used cards at least through 1984 when I left
the Mainframe world. I would imagine card systems stuck around for
even a while after that.
