Did assembler on all of them. But not as much on VM. As for DOS and it's variants, back then we were very likely to code in Assembler as we had the source and it was common practice to modify it ...

If you are running Linux I's use C/C++ just as well , or if you have a c/C++ compiler at your disposal on z/OS you're ahead of the game. You can write simple c programs and look at the .s listing and compare the code generated against a hand coded assembler. Ahh such memorable fun ... I need my milk and cookies and a nap now ..

I started on DOS (non VS) moved to VS, then NIXDORF VS Extended, then VSE, then VM, then the MVS series ... Shot dumps on them all, coded on them all. I think I'm getting old ...

You also have z/VM and (gasp!) z/VSE! z/Linux was already mentioned multiple times, so no need to repeat. :) I learned to read dumps back in College by reading dumps. It was much easier to debug COBOL and Fortran programs by looking at the LISTX than to actually check the logic of those 3 GLs... ;) Took a class given by GOAL about VSE control blocks and other such stuff, and then built on that without a mentor per se.
