It is unlikely we will ever move to this version of COBOL. The life expectancy of mainframe computing here is low.
If we were to need to make this migration, we would find the PDS/E requirement a serious obstacle without some way of mitigating the cross monoplex sharing problem. We have Development in a separate LPAR from Production. Our Endevor change management system updates the shared application load library from the Development LPAR. Further, testing in the Development LPAR relies on executing the production versions of modules not being changed from the same shared production load library. I could change Endevor to run the final copy to production in the production LPAR to avoid abending production work with an outside monoplex PDS/E update, but this would still mean the users of the shared PDS/E would suffer in the development LPAR. The limited updating of the limited shared DASD here is such that we don't even run GRS ring. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Tom Ross Sent: Tuesday, September 10, 2013 2:44 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: z/OS 2.1 and tools like COBOL 5.1, Fault Analyzer, Debug Tool, etc >Tom, > >Why convert to PDSE? I am curious? A stated IBM direction? Converting to PDSE just makes it easier to use or move to COBOL V5.1. PDSE is far better than PDS, lots of advantages, so you could view it as IBM direction, but for COBOL, that is the only thing we can do. In COBOL V5.1, we always generate parts of the object program with loadable user classes, which are only supported by Program Objects. Load Modules only support class B_TEXT or B_PRV in object programs. As Frank Swarbick suggested, it might be an option to use new PDSE Load Libraries for newer code and add the new libraries to concatenations. That would provide a one module at a time migration path, but it also might add too much complexity to application build and maintenance. The good people here on IBMMAIN would know much better than I would. Is that a reasonable option, to just start using PDSEs from one day in the future for any programs recompiled with COBOL V5.1?
