Talk:Multiprogramming with a Variable number of Tasks

I'm rewording the following quote from the page:

Originally, that was something like a 360/40 controlling a 360/65 or greater processor through a magnetic tape channel controller processor. We had this nightmare at the university I attended in the late 1960's but we junked it for HASP which ran on the 360/65 alone (really a 67 with the TSO hardware turned off) with first OS 360/MFT and later MVS (when it worked). God bless HASP, written by 5 people who knew what they were doing. ASP was a total lost at the time, designed to sell second computers, mainly 360/40s. HASP needed only one computer and MTF to start with. Later, with MVS, it was the standard. That was for a couple of years.

While it's good anecdotal evidence, it isn't really in the tone of an encyclopedic entry. I'm going to see what it takes to make it less of a POV. --Elkman - ^(talk) 21:57, 10 April 2006 (UTC)

Retitle as "OS/MVT"?

For consistency with other articles about IBM OSs and with IBM's own nomenclature. Philcha 00:13, 21 October 2007 (UTC)

Oppose; added the source to the article. --Kubanczyk (talk) 19:57, 24 November 2007 (UTC)

Also, the term "MVT®" is a registered trademark of Qualpro, that stands for Multivariable testing, a process improvement company that competes with Six Sigma. This title needs to be changed.

This is hardly an argument to consider. MVT was developed and used in 1960s, and it predates by far this book. --Kubanczyk 17:30, 29 October 2007 (UTC)

Not an issue of predating or post dating, the term MVT itself is a U.S. Registered Trademark, irrespective of the book. Juda S. Engelmayer 19:13, 29 October 2007 (UTC)

Oh, I guess we've settled that this is not a issue then. Neither U.S. law nor Wikipedia guidelines require encyclopedic articles to use (or not use) U.S. Registered Trademarks. --Kubanczyk 08:57, 30 October 2007 (UTC)

Restructure of articles about IBM mainframe operating systems

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)

regardless of the rest of the articles, this one needs to be merged into OS/360 and successors for two reasons:

• There's hardly any material here, and what there is seems to be taken from OS/360 and successors
• The code base for OS/360 mingles PCP, MFT and MVT code to such an extent that it's difficult to say much without a lot of material that pertains equally well to the other two.

Is there a reason to not make it a redirect toOS/360 and successors#MVT? Shmuel (Seymour J.) Metz Username:Chatul (talk) 20:19, 13 September 2010 (UTC)

Doesn't appear this gained any traction, removing the merge proposal - OS/360 and successors seems to be going down the path of being written summary style, about the hierarchy and genealogy of that and related technology, while this article will center around MVT.

I don't see any signs that anybody is adding real content to this article. That's just as well; anything about, e.g., Data Management, Contents Supervision, would have4 to be written in triplicate if things went in that direction. It makes more sense to write up the common code in one place. Shmuel (Seymour J.) Metz Username:Chatul (talk) 00:35, 4 January 2011 (UTC)

Rewrite of Job Control Language in progress

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 00:13, 21 October 2007 (UTC)

Merge with "OS/360 and successors#MVT"

Per discussion. Peter Flass (talk) 00:31, 3 August 2013 (UTC)
