I missed most of the thread but, is this what you mean, in REXX you can issue:
RC = LISTDSI('K248610.USER.EXEC' "RECALL DIRECTORY SMSINFO") Which might give results something like this... SYSDSNAME = K248610.USER.EXEC SYSVOLUME = PRI001 SYSUNIT = 3390 SYSDSORG = PO SYSRECFM = FB SYSLRECL = 80 SYSBLKSIZE = 23200 SYSKEYLEN = 0 SYSALLOC = 290 SYSUSED = N/A SYSUSEDPAGES = 1626 SYSPRIMARY = 290 SYSSECONDS = 90 SYSUNITS = BLOCK SYSEXTENTS = 1 SYSCREATE = 2012/102 SYSREFDATE = 2015/134 SYSEXDATE = 0 SYSPASSWORD = NONE SYSRACFA = GENERIC SYSUPDATED = NO SYSTRKSCYL = 15 SYSBLKSTRK = N/A SYSADIRBLK = NO_LIM SYSUDIRBLK = N/A SYSMEMBERS = 391 SYSREASON = 0000 SYSMSGLVL1 = SYSMSGLVL2 = SYSDSSMS = DATA_LIBRARY SYSDATACLASS = NODCB SYSSTORCLASS = TSO SYSMGMTCLASS = STANDARD /Steve From: "Shmuel Metz (Seymour J.)" <shmuel+ibm-m...@patriot.net> To: IBM-MAIN@LISTSERV.UA.EDU Date: 2015-05-13 19:10 Subject: Re: Primary allocation of a dataset Sent by: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> In <aadad469c0429c4fb23ce1486e5c10da4a5ef0f...@ing.com>, on 05/06/2015 at 01:43 PM, Fred van der Windt <fred.van.der.wi...@mail.ing.nl> said: >I want to retrieve the primary allocation of a dataset. You can't get that from the DSCB; the NVR has it for SMS datasets. There is no indication in the VTOC as to which extent came from the primary. The best that you can do is to look at the first extent and hope that it is the only extent initially allocated. Even then you can't tell the allocation units. Query: does that change on an EAV? -- Shmuel (Seymour J.) Metz, SysProg and JOAT ISO position; see <http://patriot.net/~shmuel/resume/brief.html> We don't care. We don't have to care, we're Congress.
