In PCP, MFT and MVT, SVC 99 didn't even exist! Nor TSO.
--------------------------<unsnip>------------------
Strange. ISTR using TSO under Release 18.6 of MVT. Communications were
via TCAM.

I guess one could say, in a round about sort of way, that IEFBR14 was
the front end to invoking the DASD allocation, scratch and catalog SVCs?
--------------------------<unsnip>------------------
Wrong, oh how wrong! The Master Scheduler was the "boss" of allocation
and was invoked by running ANY job step, whether it was IEFBR14, IEFIIC,
or any user-written program or any IBM or third party program. You
wouldn't say that IEFBR14 is the front end to the ALLOCAS address space,
would you?
Before SVC-99, we still had SVC-34, but the setup was somewhat more
complex and far less forgiving of errors.
