XML is even worse. Thanks for the URL. I'll be looking at that. One reason that I was looking at JSON or XML is that not every entry in a LISTCAT has the same information in it. The referenced format does seem to accommodate this because it appears to me that each line is "ad hoc" formatted. One thing that I, personally, like about XML is that you have have a DTD which precisely defines what is and what is not acceptable as input. And, at least for me, the size of the data is not overly important. Given that I have a 2 TiB HD in my at home (and more on two separate NAS boxes), and most data centers have space in the 100s of TiB (or even more), I don't know if JSON's "bloat", compared to the referenced format, is all that terrible. And, of course, for "at rest" data, the XML/JSON can be compressed (gzip, bzip, xz). If I were truly worried about it, I would probably use some sort of "delimited" format where the first field of each line identified the "schema" for the rest of the line. Such as: VL (VSAM LDS), VK (VSAM KSDS), VR (VSAM RRDS), VE (VSAM ESDS), AL (ALIAS), NV (NONVSAM), VV (VSAM VVRDS), and so on. I guess I was more trying to go with something which is current and standardized. The referenced format appears to be "in flux" and is not an ISO standard. Which reminds me that I really should go over to the ISO site(s) and see if they have had other "textual format" standard. -- Schrodinger's backup: The condition of any backup is unknown until a restore is attempted.
