When the migration plan began, Elias took Mara aside. “Don’t forget the stories,” he said. “They’re as important as the logic. If you move the code without the stories, you will only copy bugs into a new home.”

COBOL may seem like a relic of the past, but its continued relevance in modern computing is undeniable. As developers and organizations strive to maintain and modernize legacy systems, integrate with newer technologies, and leverage mainframe computing, COBOL skills remain essential. The 11th edition of "COBOL for the 21st Century" (Chapter 26, PDF) offers valuable insights into Object-Oriented COBOL, demonstrating the language's adaptability and ongoing importance.

Mara learned to respect the human artifacts intertwined with the code: maintenance notes, lunch-time hacks that later became law, and even superstitions about which copybook to touch before payroll. The team began inviting domain experts to pair-programming sessions, translating oral knowledge into tests.

Promotes modular, top-down programming using tools like pseudocode and hierarchy charts. Legacy Support:
