I programmed in Fortran for close to thirty years. What got me out of the ‘Biz’ wasn’t the programming, it was the ensuing documentation. When I first started a job that involved a one line code change plus testing and documentation took eight hours or so. When I left it was at least six month’s from start to finish plus almost a half a million dollars in overhead.
It was just too much...
Now I’m much happier doing what I’m doing.
Yes, the documentation was terrible. But everything (?) evolves even FORTRAN.
My first programming language in Electrical Engineering School was FORGO...the Daddy of FORTRAN! Ah, the Sixties!
