Programming on the Mainframe class computers is not a popular profession nowadays, it can be however an interesting one and also very profitable.

When I was preparing to start my job as a junior mainframe developer, I encountered the problem of a small amount of knowledge sources in this area, particularly available for free online. This is why I decided to start this tutorial for anyone who would like to know more about this interesting area of computer science, and also learn a little of NATURAL language, which is one of the programming languages used for Mainframe computers.

In this first post I will give you some information about the mainframe computer as well as the language and database that we will use. Soon we will also start writing the first programs and create our own databases. You can find all the parts of this tutorial in the links below:.

Mainframe programming — NATURAL/ADABAS tutorial. Intro — a few words of introduction

Systems based on Mainframes are still widely used, mainly by large organizations. The companies commonly use Mainframe for critical financial applications or for public use complex systems.

Transferring this type of application to more modern solutions is not only very difficult, but also extremely expensive.

Unfortunately, young programmers are more likely to use languages such as Java, Python, JavaScript etc. The name Mainframe refers to the first machines of this type.

It was usually large, like most computers then, and it occupied a large part of the server rooms. Mainframes in general are used when the reliability of the unit and high performance of esxentials processor are key to business eszentials. Currently, the largest manufacturer of mainframe is IBM, but we should keep in mind that this is not the only provider of this type of technology.

The extraordinary advantage of Mainframe systems is that they can be joined to form one logical super-unit.

As you can guess, to program Mainframe machines we usually use languages specially adapted for this. The latter is the language that I use at work and the one that I use writing this tutorial. Well, there are many reasons. Also the language is extremely easy to learn and use. Of course there are also downsides.

In the next part of the tutorial we will learn about the syntax of the language and write our first program. Feel free to follow my profile to be up-to-date! Please note, that I am currently working as a junior mainframe developer, so I learn the secrets of the language myself. If you see any errors in my articles, please let me know!
