Every time a new junior dev (or a panicked architect) typed that phrase into the corporate wiki, she knew. The apocalypse had been postponed another week.
: In chapters 4 and 5, you’ll learn the structured programming methods that are used in the best mainframe shops. These methods, pioneered by veteran programmer Paul Noll and others in the mid-1970s, have become an ad hoc standard in many mainframe shops.
