I am trying to understand how things work. I looked at a product (advertised on IBM-Main) that created a virtual DASD which redirected the I/O to a PC file. Cute. I asked the designer of said software how he did the virtual part of it. Answer from the developer: STARTIO.
After looking at some STARTIO samples I didn't find the answer. The past few days I was learning how boot loaders work and after looking at the S/370 books I see the SIO x'9C' instruction which made me think about STARTIO again. Now I'm reading US Patent 6,453,277 which is Virtual I/O Emulator in a Mainframe Environment. Nowhere in this patent does it mention STARTIO. It talks about FLIH hooks instead. Anyway the patent explains things in great detail. Thanks for the hints. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Anton Britz Sent: 22. marraskuuta 2008 1:57 To: [email protected] Subject: Re: Startio Question Lindy, What are you trying to do ? The BIG picture... not the story of trying to "be a Virtual Device" in zOS because there is other ways of doing the same thing, that will cost you much less effort ex. Creating your own Sub-system , with all open/clean IBM api's and examples on the Share tape. Doing it on a STARTIO level, is going way, way to deep for the type of questions you where asking earlier. Summary: Always try and explain the BIG picture before asking 6000 little questions, I think.. and then you will get better answer and save a lot of "noise" on this list.
