The most common post code (which I tend to think of as being "normal") is zero, i.e. "POST ecbaddr,0" And for that value you get X'40000000' in the ECB after the POST completes. But I do have to agree with you on the fine distinction in wording. My bad. > BTW, why is everybody boycotting EVENTS? It's just a cover function for wait/post. It is more efficient than WAIT in the case where you have lots of potential events to be waited on, but the units are still ECBs so it has most of the same pitfalls.
