Legacy code, cloud integration, and the surprising resilience of an ‘ancient’ language.
: Specifies the physical computer configuration and bridges the program to external files or devices.
For decades, the prevailing narrative in computer science was that COBOL was a "dead language." However, the 11th edition arrives at a time when that myth has been thoroughly debunked by market reality. With over 95% of ATM transactions, airline bookings, and payroll systems still relying on COBOL, the language is the bedrock of the global economy.
