If this is true, then the real question is if LE provides upward/downward compatibility. For the former, the answer is obviously yes. Regarding the latter, according to the LE Programming Guide - Chapter 2. "Preparing to link-edit and run under Language Environment - Downward Compatibility" - it does. "As of OS/390 Version 2 Release 10, Language Environment provides downward compatibility support. Assuming that required programming guidelines and restrictions are observed, this support enables programmers to develop applications on higher release levels of the operating system, for deployment on execution platforms that are running lower release levels of the operating system." I hope this helps, mario On 8/19/21 6:20 PM, Richards, Robert B. , CTR wrote: > One of my fellow sysprogs has asked me to get an answer to the follow > question: > > Will a load module compiled with COBOL v6.3 and linked with LE v2.4 on z/OS > 2.4 operate on z/OS v2.3 with LE v2.3 runtime libraries? > > Don’t shoot the messenger! 😊 > > I will, however, also ask the slightly inverse question: Will a load module > compiled with COBOL v4.2 and linked with LE v2.3 operate on z/OS v2.4 with LE > v2.4 runtime libraries? > > Bob > > > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN > ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
