It is possible to change some of the defaults within Control‑M/Restart. For example, it is possible to change the default logic for deleting data sets that are catalogued to a different volume from the volume that appears in the JCL.

For details on how to change product defaults, see the following:

• "Control-M/Restart customization considerations" in the INCONTROL for z/OS Installation Guide: Customizing.
  This topic describes how to install most optional wishes by setting parameters in the CTRPARM member. However, some optional wishes are contained in the IOADFLT member instead of the CTRPARM member.
