Course Cobol Programming

In the course Cobol Programming participants learn to develop applications in the Common Business Oriented Language (COBOL). Cobol emerged from the Conference on Data Systems Language (CODASYL) in 1959, when more and more companies in the Western World needed to automate business processes. Cobol is still widely used in banks and insurance companies, but has undergone many changes since its early days. Since the COBOL 2002 standard, Cobol also supports object-oriented programming.

    Cobol Intro

    The course starts with an overview of Cobol's typical features and program structure. The Cobol Metalanguage, Divisions, Sections, Paragraphs, Sentences and Statements are discussed.

    Data Declarations and Procedure Divisions

    Subsequently the use of Data Declarations and Procedure Divisions is treated. Attention is paid to literals, constants, variables, structured data and assignment. And also input and output and various verbs are discussed such as ACCEPT, DISPLAY, COMPUTE, ADD, SUBTRACT, MULTIPLY and DIVIDE.

    Control Flow

    Furthermore control flow constructions in Cobol with selections and iterations are part of the course program. This includes condition types, truth tables, decision tables, the EVALUATE Metalanguage and also PERFORM..THRU, PERFORM..TIMES and PERFORM..VARYING.


    After a discussion of subroutines in Cobol, it is the turn of a treatment of reading and writing sequential files.


    Attention is paid to Records, Fields, Record Buffers, Variable-Length Records and the operations SELECT, ASSIGN, OPEN, CLOSE, READ and WRITE.

    Arrays and Strings

    Finally the use of tabular data, arrays and strings in Cobol is explained and the course ends with the treatment of object oriented programming in Cobol with modules and classes.
