Lots of IBM manuals still say MVS when talking about that component. I find it convenient, for example, to distinguish “MVS datasets” from “Unix files”. They’re both part of z/OS. I’ve explained it to people as being like Darwin and macOS. Every macOS (since macOS X) is built on Darwin, Apple’s fork of FreeBSD, so you can’t get macOS without getting Darwin too. And since, unlike MVS, Darwin is open source you *could* run it without all of macOS, no one ever does. This was perhaps clearer with OS/390, which IBM explicitly positioned as an integrated package of components you previously could get separately. -- Pew, Curtis G [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
