Yes, a lot of minicomputers did that in those days. Even on the PDP-11, which had nice support for stack operations, some system- call conventions involved embedding parameters in-line. Unix did that too, although at some point an "indirect" call was added to fetch the parameter block from a pointed-to location. If you have and CDC Cyber 18 (or 1700) system software, I am desperate to obtain a copy for use with my 1700 emulation.
