Por que os Bancos não Abandonam o COBOL? A Verdade sobre a Linguagem que Recusa Parar.

"In the 90s, I was already programming, and COBOL was already the cornerstone of large systems. Decades later, many say it's outdated, but the reality behind the scenes at banks, insurance companies, and governments is quite different. In this Old School IT video, we're moving from theory to the terminal. I'll show you how a language created in 1959 by a team led by Grace Hopper still delivers efficiency and stability that the market refuses to compromise on. What you'll see in this video: • Real Structure: The divisions of COBOL (Identification, Environment, Data, and Procedure). • Hands-on: We'll compile and run a complete CRUD (Employee Registration). • Multiplatform: The same code working perfectly on Windows and Linux (Debian via Proxmox). • Technical Reflection: Why COBOL isn't about fads, it's about responsibility where mistakes are costly. COBOL didn't survive by chance; it survived because it was made for a world where mistakes are not an option." Download the source code from my GitHub and test it yourself! "Hey everyone! The COBOL CRUD code is now available on GitHub! 🚀 📥 Repository Link: https://github.com/TIdasantigas/cobol There you'll find the .cbl file and the PDF manual I promised. If anyone has trouble compiling, comment below and I'll help!" 👴💻 00:00 Introduction: The Real Legacy of the 90s 00:30 The Promise: Code, Compilation, and Practice 00:58 The "Heart" of the World Financial System 01:34 Who was Grace Hopper?
