FSVO 3rd; OS/360 had it's own spooling support, making JES1 the 4th.

Alas!

They chose to use the native spooling of OS/360; the ASP and HASP upgrades
were done by different groups.

The name SVS was already used in OS/VS2 1.0, and several releases of MVS
came out while SVS development was active.

No. The CI did normal VSAM macros against an ACB. The interface to the
subsystem was the same as if the application programmer had opened and
used an ACB directly.
