You're missing the point; the TMP does not allow two command subtasks to be ready concurrently. That's very different from how applications normally manage their subtasks. TSO's rules about authorized and unauthorized commands are clearly relevant because one of those rules ensures that there can never be two command tasks running concurrently.

TSO shouldn't normally kill the command on an attention. S13E & S33E are "normal" in many cases (outside of TSO - I'm not sure within TSO), as it's sometimes easier to just DETACH rather than coordinate a "proper" subtask shutdown. So that may or may not indicate a problem. TSO supports multi-tasking as much as jobs or STCs do; commands are indeed ATTACHed & DETACHed; and there are a few TSO/TMP tasks running all the time (see above). In any case, TSO's particular rules about authorized commands aren't relevant here. For the original problem, I don't know anything else. You might try it from a READY prompt if you haven't yet. sas On Mon, May 20, 2019 at 6:39 PM Mike Shaw <[email protected]> wrote: > On 5/20/2019 3:37 PM, Seymour J Metz wrote: > > No and no. > > > > TSO does not support concurrent execution of tasks.
