Cobol Programming

In the course Cobol Programming from SpiralTrain participants learn to develop applications in the Common Business Oriented Language (COBOL).

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.

Subroutines

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

Records

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.

Audience course Cobol Programming

The course Cobol Programming is intended for anyone who wants to learn programming in the Cobol programming language.

Prerequisites Course Cobol Programming

To participate in this course basic knowledge of programming in another programming language is beneficial to understanding but is not required.

Realization Training Cobol Programming

The theory is discussed on the basis of presentation slides. The theory is further explained through demos. After discussing a module, there is the possibility to practice. Course times are from 9.30 to 16.30.

Certification Course Cobol Programming

After successful completion of the course the participants receive an official certificate Cobol Programming.
