Select the Warn when rename target could be a GDG check box to display a warning.
Should a warning be displayed when a user attempts to rename a data set to a new name that matches the naming convention of a GDG generation? The renamed data set may become a valid generation if it matches the naming convention of an existing GDG data set. If the new generation causes the LIMIT parameter value specified when the GDG was defined to be exceeded, the system will take action based on the SCRATCH/NOSCRATCH and EMPTY/NOEMPTY parameters that were specified when the GDG was defined. This action may result in one or all of the existing generations being deleted or uncataloged.
The default is selected.
