Better check your arithmetic, Ed :-). SDWARC4 is 336 bytes long in z/OS 1.6. It is 360 bytes long in z/OS 1.7. And SDWABEA is within those additional 24 bytes. So you either need to look for "am I running on z/OS 1.7 or later" such as by bit CVTZOS_V1R7 being on, or (as EREP would have to do since it looks at SDWA's collected across systems), if SDWAVID >= SDWAVS10. Once you're able to look at the field, then I agree that you look to see if it's non-zero to see if there is anything of potential interest in it, recognizing that it is only architecturally non-zeor for a program interrupt. It is true that the SCPINFO has an indicator of PER3, but I'm not sure why anyone architecturally cares if that bit is on; that does not mean that SDWABEA even is present. You could be running z/OS V1R6 on a machine and the SCPINFO PER3 bit could be on, but that does not imply z/OS supports it on that release.
