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)
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. Anything about the pre-DOS System/360 operating systems would also be appreciated.
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 00:44, 21 October 2007 (UTC)
I started editing this article because I didn't agree with some of the information on DOS, then I realized that the discussion of DOS really didn't belong here and deleted the last paragraph.
Is it true that most BOS users upgraded to DOS? I'm trying to make sense of the chronology, but it appears BOS was the only OS available for System/360 for the better part of a year. Did early adapters run BOS until either OS or DOS were available? Peter Flass (talk) 12:24, 12 July 2011 (UTC)
