SOURCENAMES: Specifying the compaction-control qualifier of the source data set

Explanation: SOURCENAMES(name1,name2,...) is an optional parameter specifying the compaction-control qualifier of data sets that should be compacted with the table for source data sets. For name1,name2..., specify the compaction-control qualifiers of the data set names of those data sets you want to compact with the table for data sets that contain source code for programming languages. For example, you could specify BAS and ASM as qualifiers. For generation data group data sets, this compaction-control qualifier is the next-to-last qualifier of the data set name. For all other data sets, this compaction-control qualifier is the last qualifier of the data set name.

SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.

SETSYS default: None.

DFSMShsm default: If you do not specify this parameter on any SETSYS command, the DFSMShsm default is that the general compaction table can compact the source data sets.
