For the trivia buffs: the PICK database/operating system (which was a thing of beauty and its fall from popularity was much lamented by many, as was the decline of the Revelation series of database environments based on it) was written by someone called Dick Pick working on commission from the Pentagon, which needed a system to keep track of its bombing campaigns (some of which were secret eg Cambodia and Laos prior to 1970) in Indochina. Hence the starting date for the epoch in PICK. True! One nice thing about PICK was that all of the programme code, table parameters, screen designs and everything else used to implement an application were all stored as records in the database. The database was the operating system and the operating system was the database. Hence Oliver's ability to go in and fix things.
