Learning COBOL with Examples - Part 2: FILE I/O

The previous post in this series was about learning the basics of the COBOL programming language. Now I will cover a very important and essential part of COBOL - File Input / Output (I/O). I find it really interesting, as I haven't seen any other language which makes it that easy to read ...
