I'm at the age where the college I went to required us to take JCL, but it was already on its way out. I also took IBM 360 assembly language, which was WAY MORE high-level of a language than I was expecting it to be. Before then, my impression of assembly instruction set were from 6809E and 6502. In comparison, IBM 360 was a dream. But I never worked with it. It was just a class. The other thing that was interesting is that unlike the rest of our assignments which we could do in the lab, this one we had to send the code to a computer in a different city, which ran the job, and came back with results 4 hours later. You had only 4 runs to get your code to work. The most interesting about part of this story is that the every next semester after me, the same IBM 360 assembly language class use an IBM 360 emulator that ran on IBM PCs (this is at time of real-mode 640K DOS). So if I had just waited a semester, I could have done my assignments using an emulator on the PC.
