Explanation

OUTDATASET(dsname) | SYSOUT | TERMINAL are mutually exclusive, optional parameters that specify the output location for the list.

OUTDATASET(dsname) specifies the name of the data set where DFSMShsm is to write the output data. For dsname, substitute the fully-qualified name of the data set to receive the HLIST command output.

If you specify a data set that does not exist, DFSMShsm dynamically allocates and catalogs an output data set with the following characteristics:

Data set name specified (dsname)
Record format of fixed-blocked with ANSI control characters (FBA)
Logical record length of 121
System-reblockable if DFSMShsm is running with DFP 3.1.0 or a subsequent release; otherwise, block size of 1210
Primary allocation of 20 tracks
Secondary allocation of 50 tracks
Unit of SYSALLDA

If the data set already exists:

The data set must be cataloged and on DASD.
The data set record format must be FBA and the logical record length must be 121.
The data set is system-reblockable if DFSMShsm is running with DFP 3.1.0 or a subsequent release and the block size must be 0; otherwise, the block size must be a multiple of 121 up to a limit of 32K.
The user can choose the primary space allocation.
If DFSMShsm needs additional extents after the primary space allocation, DFSMShsm uses a secondary space allocation of 50 tracks.
If the data set does not contain data, DFSMShsm starts writing output data at the beginning of the data set.
If the data set contains data, DFSMShsm writes the output data after the existing data.

SYSOUT specifies that the list is to be printed to the specified system output class. For class, substitute the alphanumeric character for the system output class you want.

TERMINAL specifies that the list is to be printed at your terminal.
