my memory is that DSM-11 is an operating system
all its own, not just a language processor running on top of a standard OS like RSTS.
In the late 1980s and early 1990s, we used DSM running on VMS 4.7 for a
nationwide (United States) mortgage credit reporting system.
DSM-11 on the PDP-11 was an OS all its own. I just looked in my
Software Handbook and on the VAX it was a VMS Language Processor.
That's pretty much what it has become today although it did start
out as a complete system running on bare iron.
