In addition to other responses, another source of information is Jim Elliott's page: https://jlelliotton.blogspot.com/p/cmos-processor-table.html Jim maintained the page on the IBM web site while he worked at IBM. He still maintains it now that he has left IBM. For your question, I would use either the Reference Summary corresponding to the model you are running, or Appendix B of the Principles of Operation for that model. >(I have a zBC12 and get a SPEC EXCEPT on a SRST/Search string) As others mentioned, a Specification exception means that the instruction is used incorrectly. It does not mean that the machine does not support the instruction. -- Tom Marchant
