Summary

I have been working in COBOL development since the 1980s – back when even in my business informatics studies the fundamentals of programming logic were still taught in COBOL. Afterwards, I developed several hundred thousand lines of COBOL source code, as back then there were hardly any business-oriented software solutions for small and medium-sized companies. So, starting in the 1980s, a complete inventory management system in COBOL was built, including open item management, dunning procedures and interfaces to financial accounting.
