    Herb Karr called up. Now, I knew Herb from General Electric days. He was sort of a wheeler-dealer, and I don’t mean that as necessarily derogatory, but he was more interested in making money than producing theorems, which is fine. There is an important role in life for people like that. When I was at General Electric, consulting for the Computer Department, he was at General Electric TEMPO [TEchnical Military Planning Operation] in Santa Barbara. I was a consultant to him. He had some other operations research types, RAND types, consulting for him also. It was a fun group. He later moved to Planning Research. I had moved back to RAND. He moved to Planning Research, and he got fired. He was looking for a job. I said, “Would you be willing to write a programming manual?” He said, “Sure, I need a job.” So SPS-I was done, and we were now working on SPS-II, later called SIMSCRIPT. We asked him to write a programming manual for SPS-I. He said, “By the time I finish the programming manual, SPS-II will be ready. Let’s just write a programming manual for SPS-II.”
