Okay, I uncharacteristically have to respond to my own post, because I happened to reread it in the "threads" tab and it jumped out to myself just how wrong it sounds, even though it was upvoted. I had edited it before hitting send, and apparently did not notice that I kind of damaged the meaning. So to be clear, what I meant to say was that for a small hobby I dived relatively deeply into it (i.e. I see others messing with it for fun not caring that much about e.g. JCL), and that I wet my feet enough that if I put the serious work in, I could see myself eventually becoming productive in the COBOL and mainframe world. Just because rereading it, it sounded like I said I became mainframe proficient to a commercial level by playing around with a many decades old MVS version on Hercules, which is hilarious.
