The key of the discussion was that after the dataset has been allocated, you can retrieve the info of the primary extent of that moment, but not the primary space that was requested at allocation time, which is not the same because of several reasons (primary space in up to 5 extents, adjacent extent merging, RLSE processing, DSS extent consolidation etc.)

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.
