Read-only variables on a data set rename

On a data set rename using &ACSENVIR=RENAME, not all read-only variables are passed to the ACS routines.

The following read-only variables are passed to the ACS routines:

&ACSENVIR
&APPLIC (set by ACS routines)
&DEF_DATACLAS (set to null by ACS routines)
&DEF_MGMTCLAS (set to null by ACS routines)
&DEF_STORCLAS (set to null by ACS routines)
&DSOWNER
&DSN
&DSORG
&DSTYPE
&EXPDT
&GROUP
&SYSNAME (set by ACS routines)
&SYSPLEX (set by ACS routines)
&USER

The following read/write variables are also passed to the ACS routines:

&DATACLAS
&MGMTCLAS
&STORCLAS

During rename processing, the STORCLAS ACS routine is not called or redriven. However, redriving the MGMTCLAS ACS routine on a data set rename invokes the management class ACS routine when an SMS-managed cluster, generation data set (GDS) or non-VSAM data set is renamed. Catalog management invokes MGMTCLAS ACS routines during rename processing. Refer to Access Method Services for more information.
