JCL or DSN Catalog?
For output datasets, JCL parameters always override corresponding DSN Catalog information.
However, JCL period retention must be greater than zero to override a DSN Catalog value.
For input datasets, DSN Catalog values override any corresponding JCL parameters, with the
following exceptions:
•
EXTENT size (DLBL or DD SPACE parameter)
• density (TLBL)
• block size or CISIZE (DLBL or DD DCB parameter)
•
period retention (days) and expiration date
