I don't feel a whole lot of need to answer this, as TCBECB is not a programming interface so you should not be relying on the contents of that field or current system behavior in regard to that field. But, for what it's worth, it is definitely the case that the normal system processing of "detach" happens to set TCBECB to 0 after posting the attacher's ECB.. Also, in case you weren't aware, an ETXR gets control after the attached task has completed termination. That means that all task-related storage owned by that task has been freed. <SNIP> Timing is everything. Just as this thread came up, I got handed a SA03 problem to diagnose and fix. So when I say that "I'm glad you don't feel a lot of need to answer this", I say it with tongue firmly in cheek. Sometimes one isn't trying to use a field that is not part of the programming interface, sometimes we have to use one of IBM's blessed OCO items to debug a problem that we have come across.
