COBOL is easy to learn if you already know how to program. What's a bit harder is learning the mainframe environment it's deployed in. It's not like Unix or DOS at all.
Yes, this exactly. Whenever I tell people I'm a mainframe developer, they always ask how they can learn COBOL. Oh, that's the easy part. The environment is very different and takes a while to get used to, but it's where COBOL thrives.
