Data Division Level numbers Describe the relationship between the fields in the record Elementary Item - cannot be further divided Group Item - can be further divided Use 01 to 49 01 denotes a record as a whole 02 -49 used for fields within a record Elementry numbers must have picture clauses groups cannot have picture clauses

Data Division WORKING-STORAGE SECTION defines any data name that does not appear in a file stores results of calculations, flags, switch control, constants Used to define print lines Intermediate data storage Filler - can use as a field name, not referenced anywhere else typically holds spaces or constants
