thanks! i've looked on the web.... startio got 5 million hits, most pointing to Microsoft... but I tried again and found a wiki page http://en.wikipedia.org/wiki/Start_Input/Output
not very useful, but still I'll look harder. but if I want to "fake" a device, like tape or like a dasd that you use, then I have to use startio, no? just for me it sounds like something interesting to play around with. and crash my system? really. I've tried, but no luck. I even tried overwriting what I thought was critical memory and no luck. but I was playing around with an SRB and managed to put the system into a spin loop, whatever that is. but seems the system corrected itself. unlike windows. :-) -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of shai hess Sent: Sunday, June 19, 2011 9:43 PM To: [email protected] Subject: Re: Some tests with MFNetDisk PRO If you look at the STARTIO macro you need to supply IOSB and SRB. You need to feel all the value in the IOSB and the SRB. You need to fix your CCW and change all the address to real. You need to supply routine which will receive control in some stage of the IO. (PCI, END, ERROR etc..). You need to comply with the bits in the IOSB and the routines and your CCW. I am sure that if you dig in the internet maybe you will see some example about it. I do not understand why there is no example of startio. The only reason is that the STARTIO is not so famous compare to EXCP, EXCPR and all the other access methods. Very small number of users will want to deal with STARTIO. developing STARTIO will crash your system many times until it will work.
