                 3.1 The IDENTIFICATION DIVISION
                 3.2 The ENVIRONMENT DIVISION
                 3.3 The DATA DIVISION
                 3.3 The PROCEDURE DIVISION

COBOL program code is divided into four basic division: IDENTIFICATION, ENVIRONMENT, DATA, and PROCEDURE divisions. The identification division is required, but in theory the others are not absolute (although you won't have much of a program without any procedures or data!).
