LISTCAT Usage

Not all data set attributes are stored within catalog. Some data attributes such as allocated space are maintained in the Volume Table of Contents (VTOC) and take presedence over reported cataloged values. See IDCAMS DCOLLECT or similar service for listing additional data set attributes.

For automated solutions, IBM® recommends using the Catalog Search Interface (CSI) which provides compatibility and toleration support across releases. See z/OS DFSMS Managing Catalogs for more information on using CSI.
