When all else fails, try Google. I found the following url for an IBM book: http://publib.boulder.ibm.com/infocenter/zos/v1r13/index.jsp?topic=%2Fcom.ibm.zos.r13.ieam700%2Fieemsg.htm This is the name of the book: z/OS MVS System Messages, Vol 7 (IEB-IEE) SA22-7637-21
In this book I searched for "per zero" and found this text: ID=xxxx The SLIP trap identifier entered in the DISPLAY command. type The type of SLIP trap: NONPER Not a program event recording (PER) trap. PER-IF PER instruction fetch trap. PER-SA PER storage alteration trap. PER-SB PER successful branch trap. PER-SB1 PER 1 successful branch trap. PER-SBT PER 1 successful branch into (SBT) trap. PER-SAS PER storage alteration by STORA (SAS) trap. PER-ZAD PER zero address detection trap. Next I would suggest you Google and/or search IBM books for "PER-ZAD".

I've tried finding about this using the -08 version of the Principles of Operation. I got a few hits, but nothing which described what it actually __does__. I can guess from the phrase, but I'd like something documented. John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
