It does not depend on a specific operating system.<\/p><p>Highly intuitive, COBOL uses English words and phrases as syntax for keywords and constructs.<\/p><p>This natural language-inspired syntax structure is based on Grace Hopper&#8217;s work in the 1940s on FLOW-MATIC: a text-based data processing language.<\/p><p>Languages such as <strong>COMTRAN and FACE had a strong influence on the design of COBOL.<\/strong><\/p><p>Previously, each operating system had its own programming language. This could be a hassle for companies working with multiple OSes.<\/p><p>It was to remedy this problem that the COBOL project was born. Its portability and ease of use have made it a widely-used tool for companies in many sectors.<\/p><p>Since its appearance in the 1950s, COBOL has gone through several versions. The first was COBOL 60, followed by COBOL 61, COBOL 65, COBOL 68, COBOL 74, COBOL 85, COBOL 2002 and COBOL 2014.<\/p><p>Over the years, COBOL has evolved to meet the changing needs of computing. Features such as file processing, data management or complex arithmetic and string manipulation have been added.<\/p><p>This language has become very popular in business management systems, notably for financial transaction processing applications, payroll systems and databases.<\/p><p><strong>COBOL<\/strong> also played a crucial role in the computer industry because of its backward compatibility. Older COBOL programs could be easily adapted to new versions of the language without the need for major modifications.<\/p><p>This feature enabled companies to maintain their existing systems while gradually integrating new functionalities.<\/p><p>However, with the emergence of new programming languages and technologies,<strong> COBOL<\/strong> lost popularity from the 1990s onwards.<\/p><p>More modern, object-oriented languages began to dominate the programming landscape, while COBOL was often perceived as an obsolete language.<\/p><p>Nevertheless, it hasn&#8217;t disappeared completely. Many companies and financial institutions continue to use<strong> COBOL-based systems<\/strong> because of their reliability and ability to handle massive volumes of data.<\/p><p>Some of the most critical infrastructures, such as payment systems and social security systems, are still based on <strong>COBOL<\/strong> programs.<\/p><p>COBOL&#8217;s development is now complete, but its programs are still in use and may continue to exist until software is ready to migrate to a new alternative.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6991f3f elementor-widget elementor-widget-image\" data-id=\"6991f3f\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.15.0 - 02-08-2023 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/datascientest.com\/wp-content\/uploads\/2023\/06\/cobol-datascientest1.jpg\" title=\"\" alt=\"\" loading=\"lazy\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\"><\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-38ae98a elementor-align-center button-principale elementor-widget elementor-widget-button\" data-id=\"38ae98a\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm elementor-animation-grow\" href=\"https:\/\/datascientest.com\/en\/data-courses\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-text\">Find out more about our Data training courses<\/span>\n\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-e6b8543 e-flex e-con-boxed e-con\" data-id=\"e6b8543\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0e2ce28 elementor-widget elementor-widget-heading\" data-id=\"0e2ce28\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">How does COBOL work?<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f22935e elementor-widget elementor-widget-text-editor\" data-id=\"f22935e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>A typical <strong>COBOL program<\/strong> follows a hierarchical structure comprising multiple interrelated components.<\/p><p>Firstly, the language has 78 characters.
