How popular is COBOL?
I&#x27;ve been working in environments that use mainframe systems for a long time. I&#x27;ve read COBOL code to get an idea of what&#x27;s happening downstream, but never actually written a line of COBOL myself. I&#x27;ve always wanted to know: In a modern context, does COBOL have any advantages for applications like transaction processing?<p>I understand that it&#x27;s not ideal from a language point of view, but does it have any properties that make it a great fit for the job? Does COBOL on a mainframe have particular properties that make it good for concurrency, validation, etc?
