  • Course Cobol Programming : Content

    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.

    Course Forms

    All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.


    We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.

    Course times

    The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.


    We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.


    Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.


    The course includes lunch that we use in a restaurant within walking distance of the course room.


    The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.


    At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.


    The intellectual property rights of the published course content, also referred to as an information sheet, belong to SpiralTrain. It is not allowed to publish the course information, the information sheet, in written or digital form without the explicit permission of SpiralTrain. The course content is to be understood as the description of the course content in sentences as well as the division of the course into modules and topics in the modules.
