About SlimeNENC

SlimeNENC converts legacy source code to modern targets bit-exactly:

99.9995% acceptance rate on the NIST CCVS85 reference corpus
Dialect-specific COMP-3 rounding dispatch — IBM HALF_UP, Unisys MCP HALF_EVEN (banker's), and 11 more historical mainframe dialects
Tamper-evident audit chain (patent claim 9)
WASM/WASI execution for environment-agnostic deployment
Designed to eliminate the "one-yen-off" rounding problem that breaks financial and healthcare COBOL production migrations

Request a converter pair

Tell us which source → target pair you'd like us to build (e.g. Fortran → Java, PL/I → Java, RPG → Java, Ada → Rust). Aggregated demand is public (source, target, count) — your identity and use case are admin-only. We use this signal to prioritise new converter development.

Current aggregated demand: /request-stats (JSON, anonymous)

License inquiry

After this form is submitted, our team will contact you within 2 business days (evaluation, contract, demo). After review an API token is issued and sent via email.
