Let me see if I can help clear it up any. Or make it worse. ( I would bet... oh never mind!)
If you always use CPLOAD MODULE as the name and that is the last module used to IPL with -AND- a CP SET IPLPARMS was NOT used to change the location of it, then CP will load that module on a re-IPL either via an abend or SHUTDOWN REIPL. What this means is, if you replace the CPLOAD MODULE with a new CPLOAD MODULE, CP will load it when an IPL is done. It can't/won't load the "old" version of it because it is not there anymore; an IPL is just that - an Initial Program Load. It loads the program fresh - in this case the CPLOAD MODULE. Nothing is preserved when a re-IPL is done. The "old" nuc is burnt toast on an abend/re-IPL and the load process gets a fresh copy from the parm disk whether it is the original CPLOAD, a new one or a plain text file with your grocery list in it. _______________________________________ James Vincent Systems Engineering Consultant Nationwide Services Co., Technology Solutions Mainframe, z/VM and z/Linux Support One Nationwide Plaza 3-20-13 Columbus OH 43215-2220 U.S.A Voice: (614) 249-5547 Fax: (614) 677-7681 mailto:[EMAIL PROTECTED] The IBM z/VM Operating System <[email protected]> wrote on 11/07/2006 11:12:37 AM: > [email protected] > > Maybe I'm misunderstanding the question, or John's answer.
