This was what I was trying to tell that the application program could begin from any location of the available RAM space, which was only known to the programmer/user. Now, there would be a need of an interactive scheme/routine that would allow enetering that location in a vacant RAM location (s) from where the address woild be loaded into PC. You wrote that routine much earlier than I. ( I wrote in 1985/86).
In 1992, for the first time in the post graduate class, the professor was explaining to us what was a DOS (Disk Operating System). He simply said that an operating system was any routine that helped the computer user to execute his application program like running the Word Star text processing software or the Princess Game.
So, the small routine that you wrote for 6802 to jump to the beginning point of your loaded program was certainly an Operating System. Hearing that your Supervisor would auto promote you in the next upper class rather than declaring you failed!
