Mark, Many VM releases ago, VM Development wanted to have all customers benefit from performance improvements for some of the items that were written in REXX. You know about these parts like VMLINK, NOTE, SENDFILE, FILELIST and many others. However, we could not assume that all customers would install the REXX Alternate Library and customers would want to use these parts even before they got around to installing the REXX Alternate Library. So VM Development created a DMSRTPRC which is a library which is sufficient for the compiled REXX parts that are shipped with the VM product. It is not to be used by our customers for their own use because it is not supported for general use. There is no guarantee that your compiled part will run if you edit it to use DMSRTPRC. VM Development will not service DMSRTPRC if it does not work with your compiled part. We will service it if it fails with one of the parts that are compiled and shipped as part of VM. pdb (Doug Breneman) z/VM System Test IBM Endicott, NY
From: "Gillis, Mark" <mark.gil...@ca.com> To: IBMVM@LISTSERV.UARK.EDU Date: 04/13/2011 04:26 PM Subject: Re: Running REXX compiled in z/OS in CMS Sent by: The IBM z/VM Operating System <IBMVM@LISTSERV.UARK.EDU> Thanks, Tracy. It sounds like we'll just need to require our customers to install the alternate library as a pre-req to our product. I'm a bit confused by all this though - IBM provide compiled REXX that has DMSRTPRC in the header and this doesn't seem to require the alternate library. If I edit a compiled REXX program and change EAGRTPRC to DMSRTPRC it works fine. If either works, why do we have an alternate library?
