Specifies the DDNAME to be used in JCL to reference the site-specific listdef library. ld_name can be up to eight characters, and must conform to standard job control conventions. This library contains the listdef statements that establish the default site policy.

Specify a value for this keyword if you want to implement a site-specific policy for listdefs.

The LDFDDLN keyword is optional. If no value is specified for LDFDDLN then no installation value will be used as a default. The ZDT/Db2 default (SYSLISTD) will be used.

If you specify a value for LDFDDLN, also specify a value for at least SLDJCL1. Using the SLDJCL1 - SLDJCL4 keywords, you can build a DDNAME concatenation that comprises up to four libraries. See SLDJCL1, SLDJCL2, SLDJCL3, and SLDJCL4.

For an example, see Examples of HFM2SSDM macros.
