I was able to disable DAE using:
SET DAE=01
(the ADYSET01 member was set up to do it)

I think I need to better understand the relationships between all the different debugging datasets, such as SYSMDUMP and SYSABEND. Can you point me to the correct manual or PPT?

If you effectively own the box, disable DAE. This can be done with an MVS 
command (which I can't remember).
Second -- SYSMDUMP should be written to a dataset, not SYSOUT=*.
I normally use SYSABEND SYSOUT=*, or I set a SLIP trap to generate an SDUMP for 
my S0c1.
Alternatively, if you don't have access to the HLASM Toolkit's debugger, I can 
supply my instruction trace code. Contact me offline at [email protected] if you 
are interested.

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.

Well, I started with formatted (there were no unformatted dumps and no IPCS) 
dumps, and they are a royal pain. Except for the most trivial cases, it's a lot 
more convenient with IPCS.

Hi Tony,
I frequently use the procedure Gary mentioned which results in a formatted 
dump. I suspect IPCS might be overkill, but I don't know your situation. I'm 
sure folks exist who cut the teeth on MVS dump reading by starting out with 
unformatted dumps and IPCS, but I don't know of any. The formatted SYSUDUMP is 
pretty straightforward.

If you have any questions, there is a section in the chapter on ABEND dumps in 
this manual... 
https://www-01.ibm.com/servers/resourcelink/svc00100.nsf/pages/zOSV2R3ga320905/$file/ieav100_v2r3.pdf
  The zap utility mentioned is also in there if you need it, and called SPZAP.

HTH,
Mike
