You missed out on all the fun. Our college computer was a 360/67
with virtual storage, and we did most of our programming in PL/1.
Fabulous programming language in terms of capability and ease of use,
but a huge resource hog.

at that same time, based on what I knew from some friends
working there, was running OS/360 using MVT, which was Multi Variable
Tasks which allowed the operator to create partitions and then delete them
as needed. As I understood it they quickly switched to OS/VS2 when IBM
upgraded the hardware which gave them the ability to better use memory.
Then later they switched to OS/MVS which stood for Multiple Virtual Spaces
(I think) which I stopped working with in the late 80s on the 370.

Thanks for setting up my walk down memory lane.

Hey, this is a lot more fun than politics, if not as much fun as poker.

I'll have to grant you that even the early members of the OS/360 family met
my bare minimum for maybe being an operating system: they would regain
control without cooperation from the user program, and they could
re-allocate resources on-the-fly. But until very very late in the series it
took hand-tuned deep wizardry to get them to seem anywhere near as flexible
as the things now called operating systems (and even with deep wizardry,
real flexibility required cooperation from the user program). To even the
average systems guy, they felt like fancy loaders, multiple loaders and
time-sharing systems.


CP-67 was certainly more than that. At the remote terminals, it
supported virtual machines for each user under CMS. Then, for batch
jobs, we could submit via Remote Job Entry. System resources could
be requested and accessed via JCL, which wasn't really all that hard
to learn once you got the hang of it.
