Lindy, The child doesn't need to know anything about that ECB. The ECB specified on the ATTACH macro is used by the system. When the subtask completes and returns to the system (via the oldest PRB on the task queue issuing an SVC 3), the system will post the ECB to notify the mother task that it is safe to issue the DETACH. If the child task POSTS the ECB, and continues to execute, when the mother wakes up and issues the DETACH you will see x3E abends caused by terminating a TCB that was still running.

I wonder if I am missing something. Here is what I think: My main program does an ATTACH,EP=CHILD,ECB=ECB1 WAIT ECB=ECB1 DETACH (R1) The program CHILD does its thing and then when done POST ECB1 Which IIUC causes the main program to stop waiting. How does CHILD know the address of ECB1 in order to POST? Or do I need to pass the address as a parameter?
