What is COBOL track?
Join Exercism’s COBOL Track for access to 34 exercises with automatic analysis of your code and personal mentoring , all 100% free. COBOL is a statically typed, imperative, and procedural programming language with support for object oriented programming.
What is the shortest COBOL program?
The COBOL Report Writer Example programs using the COBOL Report Writer. COBOL Tables Example programs using tables. This example program is almost the shortest COBOL program we can have. We could make it shorter still by leaving out the STOP RUN. The program accepts a simple student record from the user and displays the individual fields.
How many exercises are there in a COBOL track?
The COBOL track on Exercism has 34 exercises to help you write better code. Discover new exercises as you progress and get engrossed in learning new concepts and improving the way you currently write. The best part, it’s 100% free for everyone. Get fluent in COBOL by solving 34 exercises. And then level up with mentoring from our world-class team.

How to Install The GnuCOBOL Compiler

This compiler transpiles COBOL to C bytecode that can run on your linux bash command line. Not all the features of COBOL are supported but most are. Run (to install): sudo apt-get install open-cobol medium.com

How to Write A Program

We will write a simple program in cobol called ‘hello.cbl’. There are a lot of strange keywords in cobol. I will explain them after compilation. medium.com

How to Compile and Run

Create the runable bytecode file with the instructions below. This transpiles our COBOL program called ‘hello.cbl’ to C then it takes the C and produces an executable object/bytecode file called ‘hello’. Compile and then run with: cobc -x -o hello hello.cbl ./hello Should output: WILLKOMMEN medium.com

Understanding The Program Structure

First and foremost to comment in cobol use the *> characters. In a cobol program there are several possible divisions. A division is just a way to break up the program into areas responsible for different things. So IDENTIFICATION DIVISION is responsible for identifying the program (docs). We are only going to use the PROGRAM-ID keyword, giving our

Declaring Variables

I will write a script below that explains how to declare and print variables. We will declare several variables in the data division (FIRST-VAR, SECOND-VAR, etc) and then print them in the procedure division using DISPLAY. PIC stands for picture (not sure why it is called this) and it is a keyword we use to define a variable. We use functions of th

Common Verbs

In cobol a verb is a keyword that does something (docs). We will cover the compute, divide, multiply, subtract, add, move, and initialize verbs. These are verbs you will use often in cobol programming to calculate, say the result of a business transaction. compute — can be used to do arithmetic and store the result in a variable divide — can be use

Conditionals

In this section we will look at if/else statements and switch statements. All this should be familiar to you if you have done any programming. You have your standard if/else, not/and/or operators, type comparisons, and switch statements. The only thing that might be a little weird are the pre-defined statements. What has essentially happened here i

String Handling

String handling in cobol is very verbose and requires a lot of typing. Let’s try it. Tallying all or just specific characters is pretty clear. The replacing keyword is also pretty clear, it replaces specified data in the string with some other data. Whats really worth digging into here is the string concatenation and the splitting. In the STRING st

Looping

We will now cover some of the looping logic in cobol. One thing I’ll mention before we get into it: We can name parts of the procedure division; these named parts, called paragraphs, can be used kind of similarly to functions or named lambda functions in python. In cobol a paragraph can contain many sentences/statements. So I think the loops are pr

Files

Files in cobol usually have a rigid structure like a table. This is because of what they were created for dealing with: well organized business data. There are a few kinds of files in cobol (docs, another example); we are going to deal with sequential files as they are the most basic. A sequential file consists of records (rows) and each record con
