Example of Primary and Secondary Filters

When you use primary and secondary filters together, the data is filtered by the primary DATASET filter first, and then by the secondary UNIT filter.

DATASET (INCLUDE (AAA.**)) UNIT (INCLUDE (3490E))

This combination would include data sets with a high level qualifier of AAA. Of this group of data sets, it would include only those referenced on a 3490E tape drive.

Note: As this example shows, when you use a primary and a secondary filter together, they do not interact with "OR" logic. Primary filters interact using "OR" logic with other primary filters, and secondary filters interact using "OR" logic with other secondary filters. However, primary filters interact with secondary filters using "AND" logic.
