Based on some predetermined values of SALES-TYPE the record will be interpreted in one of the two forms, Note that the SALES-BY-UNIT and TOTAL-SALES refer to the similar storage space. They actually represent two different mappings of the similar storage region.
The REDEFINES clause as explained above is quite common in use. Though, the clause may be simply used for the aim of conservation of storage space possibly in the working-storage section.
