OK, this is what happened. The "dump analyser" is a trusty clist written for 
IPCS by me over 20 years ago. It (almost always) works by using the chain: ASXB 
-> abending TCB -> RTWA, from where it gets the PSW and registers. In this case 
it got caught out because there was a preceding TCB with a completion code of 
0C1 but only a PRB, no RTWA and hence the mayhem. 

So, sorry for the noise but this exchange has proved very useful because I now 
know about the BEAR. Unfortunately it is not listed by either the IPCS STATUS 
or SUMMARY commands, which would have been very useful since there is a chain 
of control blocks to follow (SDWAXPAD->SDWAPTRS, SDWAXEME->SDWARC4).

Cheers

Good catch. Even after reading my Principle of Operations, it is still a good 
catch :-)

Of course, the OP discovered later that 'dump analyser picked up the wrong PSW 
'.

I wish the OP published the CORRECT dump results including the PSW and the 
registers.
