:General information on S/360 channel command words should either be in a separate article or in in expanded section of [[Channel I/O]]. It's reasonable for that article to have a simple DASD channel program to illustrate the handling of Status Modifier, but any further examples of DASD channel programs should be in DASD-related articles. Likewise, information on the CAW, CCW and IDA list formats belongs in [[Channel I/O]] and [[IBM System/360 architecture]], not in [[Execute Channel Program]], [[Execute Channel Program in Real Storage]] or [[Start Input/Output]]. If anybody writes a S/370 architecture, S/390 architecture or IBM Z architecture article then that is where the new CCW and IDAL formats belong, possibly in addition to [[Channel I/O]].
:The existing [[Channel I/O]] article is highly IBM Centric and doesn't even adequately cover older IBM systems. Perhaps it should be split into a generic article and an article specific to the S/360 family. I'd love to see someone add material on, e.g., [[CDC 1604]], [[GE-600 series]], [[UNIVAC 1107]] [[User:Chatul|Shmuel (Seymour J.)

::Agreed the [[Channel I/O]] article should be less IBM centric and would prefer expanding the article to add other "channels" to this article making the IBM Channel a specific instance. One problem might be finding an RS to combine the various "channels" in one article. A quick look at Patterson and Hennessy, "Computer Organization and Design' and Blaauw and Brooks, "Computer Architecture wasn't to helpful. Apparently today channel is a mainframe term and other than perhaps IBM it isn't much used these days.
Shouldn't this talk be moved to the [[Channel I/O]] article and not here? [[User:Tom94022|Tom94022]] ([[User talk:Tom94022|talk]]) 00:30, 9 December 2019 (UTC)
