> Worth noting even its creators say JCL is the worst language ever invented. I don't dispute that, but I'd kinda like to hear the specifics of their reasoning. I've never actually used JCL, but I'm willing to cut it a little slack because, IIRC, it literally started in the 60s as a way to specify job-execution information on a punched cards for batch processing systems that had as little as 8K of memory. What I've read about very early personal computers with similar amounts of memory makes me think it requires serious compromises to implement anything that actually works on such a system.
