Hi, I am still not sure why anybody would want to run an IBM operating system on a PC. The only possible reason is "Commercial Software" written for the IBM operating System , that you want to port to a PC platform but these days, the same "Commercial Software" on a mainframe, is available for the small/midsize platforms. So my conclusion with all these simulators/Hercules etc is that it is because we have a lot of bored and confused MVS/zOs System programmers that wants to make the whole world speak IBM. <snip> Because it allows them to develop software, or run/test software that requires S/3xx architecture, or z/Arch, without having to purchase IBM's hardware. You are a bit off on your assertion with the "only possible reason". At this point, IBM has pulled the ability of persons to do development on cheap sanctioned computing platforms. So Hercules allows that development to be done. Then that software can be moved, at a later point, to an actual mainframe. Some of these sysprogs even get involved in the support of Herc, and so learn things about hardware functions controlled by micro-code, and so get a much better feel for how things are done/should be done. It improves their understanding. Me thinks that your conclusion(s) is a bit jaded. It might be that VM, VSE, VS1, etc. programmers may want the rest of the world to stop thinking that rebooting solves 99% of the problems. Well, in my case, rebooting to Linux fixed the Windoze problems... Therefore, my conclusion is that you are a Jedi-Knight.
