Yeah, but...
I don't experience issues displaying keys using DISPLAY(MACHINE) when
responding 'Y' to BLS18160D.
I tried it just now. I initialized a dump still lying around from
yesterday (SLIP to capture an SDC2 abend in an SRB) and responded 'Y' to
the BLS18160D prompt:

BLS18160D May summary dump data be used by dump access? Enter Y to
use, N to bypass.

Same with all of the other registers that look like addresses. Not one
does not show the KEY information. I get similar results when processing
dumps in TCB mode. Pretty much everything pointed to by the RTM2WA is
included in the SUMDUMP and KEY information seems to be routinely provided.
Perhaps there is some pathological situation where that information
doesn't display?
