Perhaps you could use that? -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Charles Mills Sent: Monday, April 5, 2021 1:38 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Machine-readable flag for "development-only z/OS' [External Email. Exercise caution when clicking links or opening attachments.] I know IBM sells z/OS licenses that are for development only, such as the Z Development and Test Environment. Is there a machine-readable flag that indicates that a z/OS instance is development only? Would it be possible to write an app that, just as an example, refused to run in such an environment?
