Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp. Poughkeepsie NY -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Paul Schuster Sent: Thursday, July 28, 2022 3:15 PM To: [email protected] Subject: MODE trace entry The manual z/OS: z/OS MVS Diagnosis: Tools and Service Aids GA32-0905-50 shows that a MODE trace entry will be generated for "a change into or out of 64-bit addressing mode". Is a SAM64 instruction supposed to generate such a trace entry? I am not seeing one when a SAM64 instruction is executed. Thank you.
