Cobol & Mainframe Programming

COBOL and FORTRAN, both are pretty old programming languages, known for their use-cases. Cobol stands for Common Business-Oriented Language, whereas FORTRAN stands for Formula Translation. In this article, we will explore the core difference between Cobol and FORTRAN. But, before, we do so, let's quickly take a look at their origin history. FORTRAN was created by John Backus at IBM. He did it in 1957. It was mainly aimed at computers and hence known as a [...]

Are you looking to learn about COBOL functions? If you do, then you have come to the right place. In this article, we will explore the top 10 COBOL functions. These functions will help you take full advantage of the COBOL programming. So, without any delay, let’s get started. Most Important COBOL Functions 1. ADD Verb The ADD function lets you sum two (or more) numeric operands. Format 1: Add OPERAND-1 to OPERAND-2 As you [...]

Are you looking to program in RPG programming language for mainframe computers? Then, you have landed on the right page. But, before we go forward, let’s get to learn about the RPG programming language first. What is the RPG programming language? RPG programming language stands for Report Program Generator. It is high-level programming used for business applications. Its history dates back to 1959 when IBM developed it to replicate punched card processing. It is aimed [...]

Are you looking to learn about how to program in ALGOL programming language for mainframe computers? If you do, then you have come to the right place. ALGOL is undoubtedly one of the most influential languages out there. It became popular in the era of other influential programming languages such as COBOL, Fortran, and so on! What Makes ALGOL so special? So, what made ALGOL so special? It is because it influenced other languages and [...]

In the world of programming languages, there have always been comparisons for languages. Which one is best? Which one should I use? And so on! In this article, we will explore two popular programming languages: Fortran vs Visual Basic. Is Visual Basic and Fortran relevant now? Fortran Vs Visual Basic Key Differences Conclusion Both the programming languages are old and were most relevant when they came out. But, with time, both of them have seen [...]

Assembly language is known for low-level access to computers. As mainframes are all about performance and efficiency, assembly language is frequently used to program them. In this article, we will learn how to program in assembly programming language for mainframe computers. Pre-Requisite To Get Started Getting Started With Assembly Language Examples! Assembler Source To Executable Module So, let’s get started. Program in Assembly programming language for mainframe Pre-Requisite To Get Started Assembly language is not [...]

SAS is one of the most popular statistical suites out there. It is used for advanced analytics, a criminal investigation, data management, and so on. The SAS programming language is also popular and is used for multiple use-cases including its usage in mainframe computers. Mainframes are powerful computers used for critical applications by large applications. That’s what makes it hard to program and maintain. In this article, we will take a look at how you [...]

PL/I is a programming language one can apply to code either system-level programs for mainframe computers. It is based on the ANSI PL/I Standardization Committee X3Jl. PL/I Subset G has the approved formation of the complete language.PL/I Subset G is simple to acquire and apply. It is an extremely compact language because its object usually guarantees hardware independence. It is also more effective because programs written in PL/I Subset G are more simple to perform, [...]

Rexx was developed by IBM in the late 1970s. Rexx or Restructured Extended Executor is a programming language that carries various characteristics such as functions, support for UNIX commands, file I/O operations, debugging, and crash security. This article describes the use of REXX for mainframe computers. How to run a REXX program in the mainframe? How to execute parsing in mainframe using REXX? How to REX Loop in the mainframe computers? Types of REXX Instructions [...]

When we compare two programming languages, we must know about the intention behind the creation of that language. Even we must evaluate the usage of that programming language, and which business market is taking the major benefit of that language. The field in which language is being played; later on it shapes the language uniquely. Today we will compare two powerful programming languages. COBOL C# COBOL was developed for business applications. It has been used [...]
