COBOL

COBOL runs 70% of the world's business transactions. Modern COBOL (GnuCOBOL 3.2 / IBM Enterprise COBOL) supports JSON, XML, and Object-Oriented features.

When to Use

  • Mainframe Core Banking & Insurance Systems: Maintaining and extending mission-critical legacy financial ledger engines.
  • High-Volume Fixed-Point Financial Calculations: Executing exact decimal math without floating-point rounding errors.
  • Batch Processing on IBM z/OS: Processing millions of nightly accounting records, payroll statements, and clearinghouse transactions.
  • Modernizing Legacy Mainframes via APIs: Wrapping legacy COBOL subprograms with REST/gRPC interfaces via IBM z/OS Connect.
