You can use DSAT for displaying allocation information about data sets. DSAT will search the catalog for the entries for the data sets specified. Allocation information will be obtained from the volume table of
contents (VTOC), formatted, and displayed. If a name is an index name, all data sets below the index will be displayed.
The user may bypass the catalog search by supplying the volume serial on which the data set resides. This option permits displaying information for an uncataloged data set.
The user can select the attributes to be displayed by specifying keyword operands.
The DSAT command may be used in TSO CLIST or REXX command procedures to find the allocation of a data set or a group of data sets and set the return code to the specified value. The return code may then be tested with the
WHEN command. Output may be supressed by specifying NOPRINT. The HARDCOPY keyword may be used to direct the output to a pre-allocated data set.
The user may choose the information to be displayed by entering keywords. The information that may be displayed is:
Volume Serial on which the data set is located
File sequence number
Device type code from catalog entry
Allocation (allocated, used, and extents)
Secondary allocation (amount and units)
Data set organization
DCB (RECFM, BLKSIZE, and LRECL).
Creation date
Expiration date
Last date referenced (MVS SU 60)
Fully qualified data set name
CCHHR of the format 1 DSCB
Generation Data group data
PDS directory information.
