The DATA DIVISION has two main sections: the FILE SECTION and the WORKING-STORAGE SECTION. Additional sections, such as the LINKAGE SECTION (used in subprograms) and the REPORT SECTION (used in Report Writer based programs) may also be required.
The FILE SECTION is used to describe most of the data that is sent to, or comes from, the computer's peripherals.
The WORKING-STORAGE SECTION is used to describe the general variables used in the program.
