Perhaps you meant :>"from the SVC"? In any case, your "or" does not represent mutually :>exclusive conditions. When you return from the SVC (assuming a valid :>return code), both the ECB will be posted and also the dump will be :>complete if it is a synchronous dump.

It should say "...results in a return code :>greater than 4" which matches the wording for return code 04 that :>describes the ECB being posted for that case. In my case the dump completed (I only used SUMLIST64) with RC=0 but the ECB was not posted. -- Binyamin Dissen <[email protected]> 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.
