Just as side info… IBM added a different C compiler to zOS (MVS) to do systems stuff. They call it “Metal-C” and comes with a different RTL and assorted header files to invoke the MVS macros and address its control blocks. I don’t know anyone who uses it. We toke a look into it and went back to using assembler to interface with the system. IBM itself still uses PL/X as systems implementation language., which as far as I know has not been made available to the public until relatively recent times. As the name hints at, it’s a PL/I derivative tailored for systems and low level stuff (although the “regular” PL/I can do it without too much changes).
