Batch TMP came in with TSO/E. SVC 99 was a supported interface in MVS, but the parameter list was very different from that in OS/360 and SVS.

I'm pretty sure there was no batch TSO in MVT, but not sure if that came with SVS or (more likely) with MVS. I am also reasonably sure that SVC 99 was not a supported interface on MVT. Rather, the Dynamic Allocation Interface Routine (IKJDAIR) was the documented interface, and under the covers it used a quite different version of SVC 99 to do most of the work. But I digress...
