Isn't that similar to the JES3 IATXCSF macro?

We wrote our own. If you issue this internal macro (let's call it SUBTASK), the
next instruction after the macro is running in a subtask.
If you issue SUBTASK again, the next instruction is back in the original task.
We have a similar macro to pass control to an enclave SRB and back.
In our case, it's intended to be used like a subroutine call -- the macro calls
must appear in pairs -- so it's not quite as general-purpose as TCTL, but I'm
sure than can be done too...
