# Forth Hayes Core scoreboard | metric | value | | ----------------- | ----: | | chunks available | 638 | | chunks fed | 638 | | total | 638 | | pass | 342 | | fail | 4 | | error | 292 | | percent | 53% | - **Source**: `gerryjackson/forth2012-test-suite` `src/core.fr` - **Generated**: 2026-04-24T22:54:53Z - **Note**: completed A "chunk" is any preprocessed segment ending at a `}T` (every Hayes test is one chunk, plus the small declaration blocks between tests). The runner catches raised errors at chunk boundaries so one bad chunk does not abort the rest. `error` covers chunks that raised; `fail` covers tests whose `->` / `}T` comparison mismatched. ### Chunk cap `conformance.sh` processes the first `$MAX_CHUNKS` chunks (default **638**, i.e. the whole Hayes Core file). Lower the cap temporarily while iterating on primitives if a regression re-opens an infinite loop in later tests.
