COBOL
A programming language introduced in 1959 that continues to run widely in banking and financial systems worldwide, processing trillions of dollars in financial transactions daily. COBOL programmers are recognized as a high-demand, high-compensation occupational category.

OpenAI said its latest model is significantly stronger at understanding legacy codebases such as COBOL, Fortran and even Visual Basic, and can help developers migrate old code without breaking existing functionality.
Large COBOL systems often consist of thousands of programs calling one another, exceeding the processing capacity of a model's single context window.
The U.S. Internal Revenue Service, major banks, airlines, and a large amount of government infrastructure worldwide depend on COBOL to keep operating.
Many COBOL systems are over thirty years old and have undergone countless patch-style modifications rather than full refactoring.
A large number of core transaction systems worldwide still run on COBOL programs on IBM mainframes.
COBOL was created in 1959, led by the U.S. Department of Defense and designed jointly by academia and industry.
COBOL migration faces the difficult problem of semantic equivalence verification, and AI-generated replacement code may not cover all production environment branches.
Languages such as COBOL, Fortran, and Visual Basic still support the critical business systems of banks, governments, and large enterprises.
An AI team announced that its latest model has made significant progress in understanding and transferring low-resource programming languages such as COBOL, Fortran, and Visual Basic.
Developers proficient in low-resource languages such as COBOL are increasingly scarce, making system modernization efforts difficult.

50%UnverifiedDevelopers proficient in low-resource languages such as COBOL are increasingly scarce, making system modernization efforts difficult.
50%UnverifiedThe difficulty of modernization often lies not in syntax translation but in verifying the equivalence of business semantics; for example, if rounding rules, exception branches, or date-handling conventions in COBOL programs are not identified, they may cause financial or compliance incidents after migration.
50%UnverifiedIt is estimated that hundreds of billions of lines of COBOL code are still running worldwide, but the number of engineers who know COBOL is declining year by year, creating enormous maintenance risk.
50%UnverifiedLow-resource programming languages generally refer to programming languages whose corpus volume in public code repositories, technical forums, documentation and tutorials is far smaller than that of mainstream languages, such as COBOL, Fortran, Ada, Prolog, etc.
50%UnverifiedCOBOL was created in 1959 and was designed specifically for business data processing, and to this day it still supports mainframe systems in key domains such as finance, insurance and government.
50%UnverifiedGrace Hopper participated in the development of the early computer Harvard Mark I, invented one of the world's earliest compilers, and also promoted the standardization of the COBOL language.
