I quit coding after learning FORTRAN IV and BASIC. After that it always seemed easier to hire someone else to write programs for me. It was probably cheaper too. Of course this was back in the punch card and paper tape days. I had to carry several large boxes of cards about a mile to the computer center every time I needed to do a string of calculations. If I recall, they used a Cyber 60 machine. Or, it may have been an IBM 360. Turnaround time on most of my jobs was about 2 hours if the computer had a tailwind. If the facts be known, I really hate computers .
