What will I learn?
This COBOL Course provides you with practical skills to build, run, and maintain reliable batch programmes quickly. Learn COBOL syntax, PIC clauses, file layouts, and status codes, then apply them to real master, transaction, error, and report files. You practise JCL, SORT/MERGE utilities, debugging, testing, and safe deployment patterns so you can confidently implement complex business rules and high-volume updates in production.
