Tony 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 pw...@mweb.co.za if you are interested.

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.
