GUIDE
I added a paragraph on GUIDE, the other IBM mainframe users group, and its transition to SHARE. Technically, I suppose this might belong in a separate article; however, since the group is now defunct, such an article would never grow beyond a stub. Terry Carroll 16:59, 20 June 2007 (UTC)
 * I created a stub for GUIDE, I adapted some information from your paragraph, plus other material. Peter Flass (talk) 13:07, 23 May 2013 (UTC)

Help History of free software
The History of free software article has a section about the pre-1983 state of communities that could now be called free software communities. DECUS and SHARE seem to be two such communities, but there is little info about them in the "history of.." article.

The current content of that article is lacking in references/citations, so it would be great if anyone could add more info, with references, about the DECUS/SHARE situations. Thanks. Gronky 11:03, 21 June 2007 (UTC)


 * I added a reference to SOS and a paragraph on the SPLA to the history article. Peter Flass (talk) 23:02, 24 March 2017 (UTC)

Originally, IBM delivered only hardware
"Originally, IBM distributed its operating systems in source form[2][3][4]" suggests, incorrectly, that IBM provided basic software which SHARE elaborated. IBM never provided an operating system for the 704, the machine around which SHARE coalesced. The standard [Symbolic Assembly Program] (SAP) was written by Roy Nutt of United Aircraft. BESYS from Bell Labs was one of several operating systems that customers put on the bare iron that IBM delivered. Fortran was the only major program that I remember IBM providing in that era. It was a standalone program that booted itself, used the whole memory, and halted when done. The computer operator then manually recorded the stop location, which served as an index into a book of diagnostics. The source (written in SAP) was supplied; it was not easy to subjugate to a nonstop operating system. IBM did provide an operating system, IBSYS, for the 7090, successor to the 704. I don't have enough proper references at hand to attest these facts, but facts they are. Mdmi (talk) 03:09, 24 April 2019 (UTC)


 * I changed the wording a bit. I can't find the reference right now, but IBM provided a monitor with FORTRAN IV (I believe) that did batch processing; this might have been adapted from a user effort as well. Peter Flass (talk) 16:21, 25 April 2019 (UTC)
