Well, you already know about DAE, controlled by ADYSETxx, so I'll address the
other part.
The contents are controlled by macro parameters and installation defaults in
PARMLIB members, possibly changed with a CHNGDUMP command; normally SYSABEND
includes more data than SYSUDUMP.
Dump processing normally looks for predefined ddnames; you should only have one
of these in a step:
SYSMDUMP
Unformatted dump
Usually DSN=permanent.name
Can be read by
IPCS in batch
IPCS from the TSO READY prompt
IPCS panels in ISPF
Controlled by IEADMR00
SYSABEND
Formatted dump
Usually SYSOUT=*
Controlled by IEAABD00
SYSUDUMP
Formatted dump
Usually SYSOUT=*
Controlled by IEADMP00

Seymour, others,
Formatted or unformatted dumps does not matter to me. I actually prefer
an unformatted dump as that is what I read all the time on z/VSe.
But, as I move deeper into z/OS, I do want to learn to use some of it's
tools, such as IPCS.
Let's back up a second and let me ask what may be a basic question to
z/OS gurus.
Right now, if I put the ABEND macro into the source, it creates a new
dump in IPCS. But, if I create a SOC1 (using DC X'0000' in the code), it
does not put a new dump into IPCS.
1) Should it have put a new dump in IPCS?
2) If so, is there some 'option' in the system that may be blocking the
creation of the SOC1 dump?
3) Is there a simple way to force the SOC1 dump to go to SYSOUT as an
unformatted dump?
FYI, I am on a test z/OS system that I can IPL or change, as needed
without messing anyone up.
