ddn

Specifies the name of the DD statement that identifies the sequential data set or member of a partitioned data set that contains the filtering criteria to use. This is in the form of card-image records, in DFSMSdss command syntax, that contain the INCLUDE, EXCLUDE, and BY keywords that complete the syntax of the COMPRESS command.

Rule: You must use FILTERDD when you have more than 255 entries in the INCLUDE, EXCLUDE, or BY list keywords.
