Notes:

This example shows how FREESPACE can be reported as a table at the end of the report, via the run time option FREETAB. It is possible to make this the default option by modifying the supplied program CBLNAME.

Files shown as PERMANENT have an expiry date of 2099/366 (or 2099/365 if not defined as a retention period) - See RRR.SORTS for example.

Files with an expiry date less than or equal to today's date show as EXPIRED. - See ACCOUNTS-DATA.

The eye-catcher ***INVALID EXTENT*** on the file PRODN.HIST.FILE indicates that the extent is not totally within the disk extent limits held in the Format 4 label in the VTOC.

For the file ACCOUNTS-DATA the file serial number CBLT13 is displayed because it is different from the disk volume serial number. (Possibly caused by changing the VOLID after creation of the file).

NOT LAST VOL indicates that the file has more extents on another volume, or it has not been closed as a sequential file when created.

OWNED BY VSAM CATALOG shows that this volume is a prime or candidate volume of a VSAM catalog and thus not available for other VSAM catalogs.
