Do you have a sample output? Thanks. ________________________________________ From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Jim Mulder <d10j...@us.ibm.com> Sent: Thursday, April 27, 2023 2:41 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: IPCS formatting of I/O control blocks Yes, Wayne Rhoten enhanced that a while back. I don't remember which release of z/OS, but I have gotten accustomed to seeing it in the output from the SUMMARY FORMAT subcommand.
