The operands described in this section can be specified in any order.

LIST(listdd)

Specifies the ddname of the list data set to be produced by ICETOOL for this operation. A listdd DD statement must be present. ICETOOL uses RECFM=FBA, LRECL=121 and the specified BLKSIZE for the list data set. If the BLKSIZE you specify is not a multiple of 121, ICETOOL uses BLKSIZE=121. If you do not specify the BLKSIZE, ICETOOL selects the block size as directed by LISTSDB or LISTNOSDB, if specified, or otherwise as directed by installation option SDBMSG from ICEAM2 or ICEAM4 (see z/OS DFSORT Installation and Customization).

Refer to JCL restrictions for more information regarding the selection of ddnames.

LISTSDB or LISTNOSDB

Can be used to override the SDBMSG value for this LIST data set. LISTSDB directs ICETOOL to select the system-determined optimum block size for the LIST data set in the same way as for installation option SDBMSG=YES. LISTNOSDB directs ICETOOL to select the block size for the LIST data set in the same way as for installation option SDBMSG=NO. See the discussion of the LIST(listdd) operand previously in this section for more information on how LISTSDB or LISTNOSDB affects the LIST data set block size.

Attention: LISTSDB has no effect for SYSOUT data sets (for example, //RPT1 DD SYSOUT=*), because the system-determined optimum block size is not used for spool or dummy data sets.
