Waxing nostalgic: I loved working on mainframes back in the day. My job was a little unusual for a mainframe programmer, so maybe that's why: my team was customizing the VM/370 hypervisor and its usual guest OS ("CMS") for our employer's needs. It was mostly 370 assembly, for the OS changes, and the occasional script (or "Exec", as it was called in CMS). I wasn't doing much app development and never saw anything that looked even remotely like JCL. I loved it, and I would never go back to it.
