Pretty interesting machine, if you study its instruction set, BTW; with no

The IBM S/360/370 operating systems such as DOS/360 and DOS/VS didn't
use a stack, either, unless you were doing recursion. When we got our
VAX, I was puzzled as to why they would throw away an entire register
just to point at a stack.
