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.

Grace 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.
SMART KS retrieves actual COBOL, JCL, and data assets by calling the enterprise's own LLM and SmartTSXL's MCP server.
According to research by IBM and several industry organizations, approximately 22 billion lines of COBOL code are still running in production environments worldwide.
COBOL is the mainstream business programming language for IBM mainframes, JCL is used to define and schedule batch jobs, and copybooks are reusable data structure definition files in COBOL programs.
The large volumes of COBOL systems accumulated by enterprises in the 1980s and 1990s became difficult-to-maintain infrastructure burdens decades later because no one understood their logic.
Legacy technology stacks often require scarce and expensive specialist talent to maintain, and as practitioners of languages such as COBOL gradually retire, such talent becomes increasingly difficult to find.
Large organizations typically run legacy codebases spanning decades, involving traditional programming languages such as COBOL and RPG, which is IBM's area of strength.

The emergence of high-level programming languages such as FORTRAN in the 1950s led to concerns that assembly programmers would lose their jobs.
