message: May I please have a version history?  even if it was a comparison table or list of new features. Stephen Charles Thompson (talk) 20:43, 6 April 2009 (UTC)
replies: text: There are some notes in User:Chatul/Sandbox#IBM Announcement Letters, User:Chatul/References#Timeline and OS/360 and successors#Timeline. The announcement letters talk about new features, but including those data in a timeline would make it very large. Shmuel (Seymour J.) Metz Username:Chatul (talk) 16:47, 15 September 2010 (UTC)

message: A 31-bit mode? Don't you mean a 32-bit mode?
* 31-bit mode is correct.  The original OS/360 operating system had 24 bit addressing.  After the 31 bit mode was introduced, the 24 bit mode still had to be supported.  The high order bit was used to differentiate between the two addressing modes, so they only had 31 bits for the address rather than the full 32.  In case you're wondering, the current OS still supports 24 bit addressing mode, and applications are still used that must be run in 24 bit mode. Dave6 19:24, 10 August 2005 (UTC)
replies: text: I've gone back to "31-bit", linked to the 31-bit page, referred to it as "31-bit addressing", and cleaned that sentence up a bit in other ways. Guy Harris 17:03, 6 July 2007 (UTC)

message: Good article, but the sentence "z/OS is IBM's flagship operating system, suited for continuous, high volume operation with high security and stability" doesn't sound objective - sounds as if sourced from sales literature. Clivemacd 10:40, 29 July 2007 (UTC)
replies: text: That was my thinking on reading the article. As there is a need to indicate what it is "supposed to do", we could change it to be a general description and then indicate that IBM advertises high security and so forth. Few outside of IBM have probably tested its security, stability, etc, so there probably aren't a lot of good sources around. Nitwit005 (talk) 22:58, 5 April 2009 (UTC)

text: I think it would be fair if an indication was made that this was IBM's representation, as suggested above. That represents how IBM has portrayed z/OS and its predecessors for many years. Perhaps an alternate wording along the lines of "z/OS is positioned by IBM as its flagship operating system, suited for continuous, etcetera" would be appropriate. Or, to remove passive voice, "IBM positions z/OS as its flagship OS, suited for..." Jsavit (talk) 00:58, 6 April 2009 (UTC)

thread_title: Style Issue

message: After a big edit of MVS I concluded that the whole set of articles about IBM mainframe operating systems from System/360 onwards needed to be re-structured to  minimise overlap and to make clearer the evolutionary relationships between these operating systems (notably in memory management, which is historically a major distinguishing feature). There is already some support for this proposal. Please add comments at Talk: MVS. Philcha 23:56, 20 October 2007 (UTC)
thread_title: Restructure of articles about IBM mainframe operating systems

message: As part of the proposed restructure of articles on IBM mainframe operating systems (above), I've rewritten Job Control Language to: cover IBM's DOS/360 and its descendants as well as OS/360 and its descendants; focus more on the facilities and flavour of the 2 JCLs rather than on details of  some statement types and some of their options. Please comment in Talk: Job Control Language. I'd be particulary grateful for more info on DOS/360 and its descendants, especially after 1980 - I only used DOS JCL a handful of times, and only in the late 1970s.
The rewrite does not currently take account of Truthanado's point in Talk: Job Control Language about use of "JCL" by computer suppliers other than IBM, which may entail further restructuring of articles about JCLs. Philcha 00:26, 21 October 2007 (UTC)

message: The word ZOS which redirects to this page is a metaphysical concept introduced by Austin Osman Spare. I don't know if in computer literature the word z/OS is usually replaced by ZOS or not. But I suggest to create a disambiguation page for ZOS entry. --Sepand (talk) 06:08, 30 May 2008 (UTC)
replies: text: "zOS" is used instead of proper "z/OS" quite frequently (not "ZOS"; the first letter is always capitalized by Wikipedia). I would suggest creating Zos (metaphysics) stub. --Kubanczyk (talk) 08:03, 30 May 2008 (UTC)
replies: text: That concept can not expand as an independent entry. Only one sentence would suffice: ZOS, an idea of Perfect Man introduced by English occultist, Austin Osman Spare. Hence I think we can place it in a disambiguation page. --Sepand (talk) 08:34, 30 May 2008 (UTC)
thread_title: Suggestion for a disambiguation page

message: I see someone has added "Graphical User Interface" to the opening paragraph. While there are many software tools with GUIs with which you can carry out management tasks (IBM Tivoli range and CA Unicenter range for example), z/OS does not get shipped with them as standard. Therefore this phrase is wrong. I have removed it.

message: The deleted material was not a citation; it was a footnote. Shmuel (Seymour J.) Metz Username:Chatul (talk) 21:06, 15 September 2010 (UTC)
replies: text: Now it's a footnote.  What you had before was a reference citation.  --TreyGeek (talk) 00:48, 16 September 2010 (UTC)
replies: text: It was never a reference citation. See Help:Footnotes. Shmuel (Seymour J.) Metz Username:Chatul (talk) 11:01, 16 September 2010 (UTC)
replies: text: I'm really not sure this is worth debating.  However, looking at the state of the article after your initial edit , the list of OSes clearly appears in the "References" section at the bottom of the page and does not appear as a "Note" or "Footnote".  You may have not intended it to be a reference, but that's how it came out.  --TreyGeek (talk) 13:42, 16 September 2010 (UTC)
replies: text: I know where it appears. Did you read Help:Footnotes, which mentions having references and footnotes in a single list? The only reason that I split the list was to avoid an edit war with you; certainly other wikipedia articles use a single list for both purposes. Shmuel (Seymour J.)

thread_title: Reference vs footnote

message: Err, I don't think the labs in Perth do DFSMS, that's done out of the German labs (at least it was a few years back when I dealt with them). Perth does do ISPF, I believe. In any case, I think this whole thing is irrelevant to the z/OS entry. Why should IBM's internal development model even feature here, it's not like it matters to the OS.  — Preceding unsigned comment added by 202.81.18.30 (talk) 08:59, 16 April 2012 (UTC)

message: The terms Product Temporary Fix and Program Temoporary Fix (PTF) refer to changes larger than a single diff file in the Unix world. A PTF normally includes complete replacements for elements of the product, but may also include updates to elements. One type of update, the ++ ZAP, contains input to the AMASPZAP (Superzap) service aid and is sometimes referred to as a patch.

thread_title:  Release History 

message: My deletion of the "other features" section was reverted. The whole thing is unsourced; its few footnotes direct users to a dead link. A lot of it could be outdated. It's also very technical, the average user wouldn't understand half of it. These issues are also present in all other body sections.
The subject might not even be notable to warrant a wikipedia article at all. No sources that meet WP:GNG are listed, and I have yet to find one on google search, books and news. If none exist, then this article should just be deleted. Mottezen (talk) 07:25, 7 March 2021 (UTC)
