Not terribly well, actually. Portions of the ICF catalog structure have been undocumented for many years now (for you non-z/OS people, that's a sort of hierarchical database that points to where files live in the z/OS filesystem). I don't believe that VVR/NVR records are documented (file metadata). There was a discussion on ibm-main this week that talked about reading compressed datasets without using the z/OS API (good luck). I've never seen documentation for GRS communication -- so you can't coordinate updates with active z/OS complexes. The z/OS filesystem is made deliberately difficult to access without using the supplied z/OS API set. -- David Andrews A. Duda and Sons, Inc.
