    • David Bryant - What makes you think you're a computer programmer
      I've been programming computers since
        1969. That's the year I started attending college at CalTech in Pasadena, California.

      We actually had an online
        system in those days! The terminals were IBM 1052s -- basically, Selectric
        typewriters hooked up like teletype machines. I think the computing center
        was running a couple of IBM 360/65s. I'm not certain ... I was just a lowly
        freshman, and I didn't have access to the sanctum sanctorum in the computing
        center. That was for grad students.


      Anyway, the language we used was
        called CITRAN. It was a takeoff on FORTRAN, the Formula Translator,
        but since it had been developed at the California Institute of Technology,
        or CIT, it needed its own acronym. It was a time-sharing system. You
        entered commands, and program statements, from the typewriter. When
        your program was saved in the library, you said RUN and the system
        compiled your code, linked it, and executed it. If you had a bug, you got a
        not very helpful diagnostic message and BETTER LUCK NEXT TIME!
        CITRAN. If you wanted to print an entire program listing, with a
        cross-reference table for all the symbols, it might take 30 minutes, or longer.
        Connect time was limited, so people kept their programs simple and
        short.
