Digging around in some old boxes, I found some references to the Subsystem Interface. All are old, and may be difficult to locate. I do not have any of them in my possession, but if they are useful, be my guest.
Xephon MVS update Issues 24 and 25 (September/October 1988) explaining MVS SSI. Xephon MVS update (2 consecutive months sometime between 1991 and 1992) "Development of an MVS Subsystem by Walter Wiedermann. LY28-1496 - MVS/ESA Component Diagnosis and Logic - Master Subsystem/Subsystem Interface. GG66-3131 The Subsystem interface in MVS/SP Version 3. SR21- 1469 - A guide to using MVS/XA Interface facilities (Chapter 9). Mainframe Journal - March 1989 page 69 - Subsystem Interface Component of MVS I did say they were old..... Mike Kerford-Byrnes. P.S. 1 - Has anyone looked in the Candle Computer reports? P.S. 2 - Is there an index of ALL the topic titles for the Xephon Manuals in a given set held on the CBTTAPE site? So far all I have been able to find is the once a year accumulation - but I have to look at each month's worth until I find it. It would be helpful, especially in cases such as this to have a listing of all of the topics in, say, all of the Xephon MVS Updates held on the CBTTAPE site. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
