From COBOL to Modern Programming Languages About 26 years ago, I learnt COBOL using the book 《COBOL 语言》（上、下册） by 谭浩强 (Tan Haoqiang). Here is a portion of my transcript. At the time, I developed a simple MIS (Management Information System) using COBOL. It was one of the programming languages I worked with early in my career. Since then, I never really had the opportunity to work with COBOL professionally.
