Rawlings continues: "decided to drop the idea [of showing alternative solutions to the problem. NOMAD solution was too unbelievable for him. He published his book in 1982 ["sic:" 1981], with many fine examples of NOMAD, most of which look silly today, for they don't reflect what NOMAD was really used for in the years since: serious, mission critical applications. I used Martin's Engineer's Problem in hundreds of NOMAD classes, as I forced people to think in terms of sets of data, instead of record-at-a-time, which is how they'd been taught."
