IBM has a publication on its website describing the hardware and
operating system softwrae for its Z series mainframes. It takes an
introductory level and builds upon it. For non IBM users, or old time
IBM users, it answeres many questions about current technology.

In those days we simply called it "OS" or "DOS" (pronounced D O S). I
don't know if that was their official names or not, but everyone knew
what you were talking about. I only added the "360" to give it
context for the younger readers and to distinguish from PC-DOS.
To my surprise, the VSE writeup even acknowledged that DOS was
intended to be a temporary system until OS could be shrunken down
enough to run effectively and efficiently on machines with small
memory. To my surprise, a good deal of VSE looks just like my old DOS/
360.
