First off, why go to V5, when V6.2 is now out. In order for both compilers to co-exist, you will have to have different Dataset names for the compiler. Also, make sure that all the LE support maintenance for the newer version is installed and active on all of your systems. Lastly, you probably know, but the load libraries need to be PDSE, and new cobol wont co-exist in the same run-unit with OSVS COBOL compiled modules, so you could have some unintended problems if modules shared get upgraded that also include calls to other older modules.
There is an entire migration guide discussing all of this. We are just starting down this path too. _________________________________________________________________ Dave Jousma Manager Mainframe Engineering, Assistant Vice President david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Bill Ashton Sent: Thursday, November 02, 2017 7:58 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Enterprise COBOL version runtime **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** Hello fellow dragon-slayers! We are finally biting the bullet and getting ready to move forward with the Enterprise Cobol v 5. I know there are a lot of changes to v 5 from the world as we know it, and I will be perusing the documentation very soon, but can someone give me a quick 30000-foot view of this upgrade specific to one question? If we implement v 5 in our development LPAR before our production LPAR, can we run the v 5 programs/load modules in our v4 production system? Are there any cross-version things we need to be aware of? Thanks for helping me with this question (my management would thank you, too!).
