I meet with this brief, interesting notes about Fortran I in Paul Graham’s personal page. As the author writes, the document express the state of art when Lisp was created, that is, the beginings of the modern computer science. Fortran is the ancient programming language still active, it’s a year older than Lisp, that appeared in 1958.

“Fortran I was very simple. Programs were flat: the language does not seem to have supported subroutines or nested expressions. The Fortran if was a conditional goto”
