\u00a0What Is the WORKING-STORAGE Section in COBOL?<\/h2>\n

The COBOL WORKING-STORAGE section<\/strong> is where a COBOL program defines variables that remain available throughout the execution of the program. These variables store data such as numbers, names, counters, and totals that the program needs while it runs.<\/p>\n

Unlike temporary variables inside a procedure, values in WORKING-STORAGE persist until the program ends. This makes it ideal for storing information such as employee data, payroll totals, counters, and flags.<\/p>\n

In a typical COBOL program structure, the WORKING-STORAGE section appears inside the DATA DIVISION<\/strong>.<\/p>\n

How COBOL Programs Store Variables<\/h2>\n

The WORKING-STORAGE section acts like the program\u2019s memory area. Each variable reserves space in memory so that COBOL can store and manipulate data during execution.<\/p>\n
