COBOL programs consist of four divisions: IDENTIFICATION DIVISION, ENVIRONMENT DIVISION, DATA DIVISION, and PROCEDURE DIVISION. Each division has a specific logical function.
To define a program, only the IDENTIFICATION DIVISION is required.
To define a COBOL class or method, you need to define some divisions differently than you do for a program.
