SUMLIST64 does have 4 reserved bytes after the field containing the length. LIST64 does not. The description in the book really is correct in saying that the LIST64 format is analogous to the LISTD format. The first word is the only length field. The book indicates correctly "When LIST64=list addr is specified, the first fullword of the storage list contains the number of bytes, including the first word, in the list." I don't understand why you mention the counts since those are unrelated to lengths. I will suggest an addition to "The LIST64 storage list format is exactly analogous to the LISTD storage list format" of something like "with 8-byte-long starting and ending addresses" >As SDUMPX with a DCB only does HOME, will a SVC entered SDUMPX ever have the >ECB posted or will the dump always be complete upon return from the DCB. I don't know what "upon return from the DCB" means. 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. The doc for ECB does mention (under A-type) "posted on completion of a scheduled dump". I suspect that that is true but a bit misleading, in that the ECB is (very likely, but it would need to be verified) posted on completion of the dump, whether the dump is scheduled or synchronous. I did notice under ECB "Note that these interfaces will not be driven if the call to SDUMPX results in a non-zero return code.". I believe this is incorrect. 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.
