Indexes, Reports and CDAM Files

Index values for each index are extracted from the report by the decollating mission.

Each index value points to all report pages that contain that index value in the defined index location. Each logical report page or section is pointed to by only one value in a given index. Any page without an value that can be indexed is treated as a continuation of the previous pages in that report section. For this reason, a request to view a report based on index values may retrieve one or more consecutive or nonconsecutive report pages.

Each index value points to relevant report pages or sections in a single CDAM file. Therefore, WHEN statements that contain DO INDEX statements should select report pages that are in the extents of a single CDAM file. For information about WHEN statements, see WHEN Statements. For information about CDAM files, see Compressed Dataset Access Method (CDAM).
