Well, if you us the downlevel macro libraries then you should be fine. If you do something specific to 2.4 or 2.5 then you might have issues.
Are the 2.3 and 2.5 systems on the same hardware? ________________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of Bill Giannelli <[email protected]> Sent: Saturday, March 25, 2023 5:30 AM To: [email protected] Subject: using a v2.5 load on v2.3 I assembled and link/edited a module on a z/OS 2.5 system. Now I want to use or execute that module on a z/OS 2.3 system. Might that cause any issues? thanks Bill ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
