Deleting Datasets Using DDGEN and the DISP Parameter DD Statements for Tape and Disk Datasets
6-18 User Reference
Deleting Datasets Using DDGEN and the DISP Parameter
The DDGEN configuration option controls when a dataset is to be deleted based upon its
DISP DD parameter. The table belows shows when deletion occurs based upon the possible
DDGEN and DISP combinations. Where there is no entry in the table, no deletion occurs.
For simplicity, the table below descibes the basic DISP combinations. For those combinations
not explicitly defined in the table, the following rules apply:
If the usage-status is SHR, it will be treated the same as OLD.
If the usage-status is MOD, it will be treated the same as OLD if there is an existing
version. If there is no existing version, it will be treated the same as NEW.
The CONDCAT normal-end-status will be treated the same as KEEP.
The CATLG normal-end-status and abnormal-end-status will be treated the same as
KEEP.
