Not quite. Let me try to sort this out. 1) After an abend, the CP module file with the same name as the one that was previously IPLed will be IPLed. This is the same as issuing SHUTDOWN REIPL without any parameters (your original question). 2) If you replace the previously IPLed module file with a new CP module file with the *same name*, the new CP module file will be IPLed. 3) You cannot specify a different CP module with SET IPLPARMS. What you can do is specify a different PARM disk, which could contain a different instance of a CP module file with the same name. In this case, the CP module file (with the same name) on new PARM disk will be IPLed instead of the previous CP module file, either after an abend or when SHUTDOWN REIPL is issued without any parameters. Unless you change the PARM disk with SET IPLPARMS, if you replace file CPLOAD MODULE on the current PARM disk (or wherever it is) with a new file called CPLOAD MODULE, the new CPLOAD file is what will be IPLed either after an abend or after SHUTDOWN REIPL with no parameters.
