COBOL is a high-level programming language like C, C#, Java, Pascal, or BASIC, The name COBOL is an acronym that stands for Common Business Oriented Language. COBOL is focused on business, or enterprise, computing. You would not use COBOL to write a computer game or a compiler or an operating system. With no low-level access, no dynamic memory allocation, and no recursion.
It does not have the constructs that facilitate the creation of these kinds of program. This is one of the reasons most universities do not teach COBOL. Because it cannot be used to create data structures such as linked lists, queues, or stacks or to develop algorithms like Quicksort, some other programming language has to be taught to allow instruction in these computer science concepts
