📖About This Course
This course contains the use of artificial intelligence.COBOL is not a museum piece. It is the silent engine behind the world's largest banks, government benefit systems, insurance carriers, airline reservation platforms, and retail supply chains. Estimates put the active COBOL code base in the hundreds of billions of lines, and trillions of dollars move through it every single day. As the generation of engineers who built these systems retires, organizations are scrambling for developers who can read, maintain, and modernize the code that runs the actual economy. If you want a skill that is genuinely scarce, well-paid, and immune to hype cycles, COBOL is one of the smartest bets in software.This course is a complete, hands-on path from your first DISPLAY statement to writing production-style batch pipelines. It is organized into six sections, and each coding section opens with a short conceptual lecture that gives you the context and the "why" — the language's history, the mainframe ecosystem, its design tradeoffs — before dropping you straight into running code. You will work through the four divisions, fixed and free-form source, PICTURE clauses, edited fields, level numbers, USAGE COMP and COMP-3, arithmetic, IF, EVALUATE, PERFORM loops, paragraphs, tables with OCCURS, SEARCH, string handling with STRING and UNSTRING, and sequential file I/O. The advanced sections add the material real mainframe shops use every day: CALL and dynamic CALL, declaratives, indexed and relative files, object-oriented COBOL, embedded SQL against DB2 with cursors, the Report Writer, calling C, JSON GENERATE and JSON PARSE, and a capstone batch pipeline. The final section then closes with a focused run of deeper conceptual lectures that take you under the hood — WORKING-STORAGE memory layout, copybooks and the LINKAGE section, REDEFINES and memory overlays, the CICS and JCL execution contexts, classic patterns like control break and match-merge, and where COBOL is heading next — so the syntax you have already written finally clicks into a full mental model.This course is built for working developers, students, and career-changers who want a serious, modern introduction to COBOL. You should be comfortable using a terminal and have written code in at least one other language; no mainframe access is required because everything runs on the free GnuCOBOL compiler. By the end you will be able to read legacy COBOL with confidence, write new programs that handle data, files, errors, and databases, and speak credibly with mainframe teams in interviews and on the job.What sets this course apart is the balance of historical context, language depth, and modern practice. You will not just memorize syntax; you will understand why COBOL is shaped the way it is, where it fits in a hybrid cloud and Java or .NET architecture, and how to be productive in code bases that were started before you were born. Enroll now and add one of the most strategically valuable and underrated skills in software to your toolkit.
