:>I know that an ECB's first byte is x'80' if waiting and x'40' if posted but what does X'00' mean. When I zero out the ECB I zero out the whole word. This ECB has a PRB in it. More precisely: WAIT will not wait on an ECB with X'40' set. WAIT will store the rb address if the ECB is zero. WAIT will be OK if the ECB x'80' has the correct RB in it, and ABEND if not. Two UOW cannot wait on the same ECB. There is no problem zeroing an ECB that is not being waited upon, as long as you consider that it may be POSTed. -- Binyamin Dissen <bdis...@dissensoftware.com> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
