Assuming this is a true routine hung of the SSVT and not hooking SSI, to get to the subsystem requires that the SSIB points to your subsystem and the SSOB is a function you requested. I wouldn't even bother checking as it would require serious failures in MVS to get there. If hooking SSI, I would just pass it on. I remember code I saw that checked for MVS, and if not issued a WTO (SVC 35), which quite probably would cause other trouble to an OS that might not properly understand the SVC. -- Binyamin Dissen <bdis...@dissensoftware.com> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
