I have never has a problem using &SYSR1 anywhere ****** could have been used. Actually, the resolution of &SYSR1 occurs very early in the IPL, long before CAS is initialized.
HTH, -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Vernooij, Kees (ITOP NM) - KLM Sent: Wednesday, August 28, 2019 1:16 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Clarification on DASD mod conversion of SYSRES The difference is that &SYSR1 is resolved by CAS, which is not yet initialized at that moment. Until then, ****** does the built-in substitution.
