System environment

To run BREORG, information about the areas, sets, record types and tables to be reorganized is required. BREORG obtains this information from the schema information area (SIA) of the associated schema.

For its REORGANIZE functions, BREORG also requires subschema information (only for the recreation of multi-level LIST sets). This information is obtained from the Subschema Information Area (SSIA).
