Re: VSE sunset there was also the near-heroic efforts to save VSE by Pete Clark, Bennie Pugh, and Charles Rice. I don't think IBM "found out" the extent of VSE usage in China; I think they always knew.
> OS was being developed by an outside source Really? It also might be mentioned that there was an incentive to develop a quick-and-dirty DOS/360 that came from the shortage of machine time on the 7094 simulators (being used to develop OS/360) versus the amount of 360 hardware that was coming out of the factory but unusable due to the lack of an operating system.

Given their population, I don't think it will be disappearing anytime soon. And to think it all was just a mistake from the beginning. Back in the days when 3rd generation was "about to walk upon the scene" and OS was being developed by an outside source, IBM was concerned it was too big an undertaking and I might never even come into existence. So that they would not lose the chance to steal the market from UNIVAC which was the vendor of choice in those days and the favorite to win the 3rd generation race to the marketplace, they hastily developed DOS internally just in case and brought it out first. Unfortunately, it has always lacked at least one major control block, the DEB and so tech support has always been shackled with the burden of manually keeping track of every cylinder and track. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
