Chapter 1. Structuring your COBOL program

COBOL program consists of four divisions, each with a specific logical function:

  •  IDENTIFICATION DIVISION
  •  ENVIRONMENT DIVISION
  •  DATA DIVISION
  •  PROCEDURE DIVISION

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.
