Lizette, I can get the registers and PSW no problem. The problem I have is getting the TIME of the S0C4 so I can see which one is first. So much happens before LE gets round to taking a system dump that the z/OS trace has wrapped and I can't tell which of the 6 S0C4 abends, on different TCBs, was first. I don't think I can assume that the first to produce a CEE dump or the first to produce a SYSMDUMP was the first as they seem to preempt each other.
Anyway I got round the problem by slipping on the instruction that sets us up to fail by setting a control block pointer to zero before any of the TCBs S0C4ed. However it would have been nice to be able to tell the time of the S0C4s.
