COBOL excels at transaction processing, data manipulation, and report generation. It has a simple and English-like syntax that makes it easy to read and maintain. It also has features that support structured and modular programming, as well as object-oriented programming since 2002[^1^].
COBOL can run on various platforms, such as mainframes, servers, desktops, and mobile devices. It can also interact with other languages and technologies, such as Java, .NET, XML, web services, and databases. COBOL applications can be modernized and integrated with new systems using tools and frameworks provided by vendors such as Micro Focus[^2^].
