<snip> It's regrettable that: ... o The Ref. doesn't specify which dominates when both a JCL and a SYSTEM symbol definition are available. </snip>
I suppose I should have double-checked before my previous response. No one will ever say that it's necessarily easy to find what you're looking for, but this is documented. (from the JCL Reference https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.ieab600/jdefine.htm ): You can define names for JCL symbols that are the same as system symbol names. When a JCL symbol has the same name as a system symbol, the substitution text for the JCL symbol overrides the substitution text for the system symbol. For example, if JCL defines a symbol with the name &SYSNAME, which is also the name of a system symbol, the system uses the substitution text that is defined in the JCL. <the "bold" is from the book, not from me> Peter Relson z/OS Core Technology Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
