We’re building an open-source language layer on top of Go, designed specifically for COBOL-style workloads:
Native decimal arithmetic (COBOL-accurate)
Record structures and copybook compatibility
Batch jobs and transactional orchestration as
first-class constructs
Sequential / indexed file I/O baked into the
runtime
Compiles through Go for speed, concurrency, and
cloud deployability
Think of it as Kotlin for COBOL, or “COBOL on Go” familiar to mainframe engineers, powerful for modern developers.
Test Results so far:
NIST COBOL-85 validation: 77.61% overall (305/393 tests)
NC (Core COBOL): 97.89% (93/95)
SM (Statements): 100% (13/13)
RL (Relative I/O): 100% (26/26)
IF (Intrinsic Functions): 100% (45/45)
IC (CALL): 96% (24/25)
Compliance tests: 100% passing
Acceptance tests: 100% passing
