Which division is mandatory in COBOL program?

What are the four division of COBOL?

Where do data items belong in COBOL data division?
(2) WORKING-STORAGE SECTION All the data items used in the program should define in WORKING STORAGE SECTION ( If those fields not belong to FILE SECTION or LINKAGE SECTION ) (3) LINKAGE SECTION When program designed to receive data from runJCL or calling programs, appropriate data items need to be defined in this section.
What does input output mean in COBOL Division?
INPUT-OUTPUT Section contains the definition of the files which we use in the input and output of the program. We also call INPUT-OUTPUT as the Logical files in the Program. These Logical Files must be linked to an external device where that file is located physically. 3. DATA DIVISION Data Division describes the data items used in the program.
What is the procedure division in COBOL used for?
Procedure Division Procedure division is used to include the logic of the program. It consists of executable statements using variables defined in the data division. In this division, paragraph and section names are user-defined.
How to define the structure of a COBOL file?
(1) FILE SECTION (2) WORKING-STORAGE SECTION (3) LINKAGE-SECTION (1) FILE SECTION For Every file used in the program, we should have a entry in this section. Define the structure of the record of each file. We will explain about this section more in COBOL-FILES chapter.
