Cross tabulation edit
I spent a day in the late 60's producing "cross tablulations" (what we know in excel as a "pivot table") for a sociologist using this or a similar machine. Apparently that was how it was done at the time. I went home that night and wrote a short Fortran program (about 100 lines I think) that performed the same work, wrote up some simple use instructions, gave it to her and said something like, "use this and you will not need me anymore". It was an early piece of open-source software. --AJim (talk) 15:44, 8 September 2011 (UTC)
