# Nova128 Diagnostics

Generated from `src/common/diagcat.inc` by `scripts/build-diag-test.ps1 -UpdateDocs`.
Do not edit by hand. Numbers are stable: never renumber or reuse one.

Each `%` is replaced by an argument such as a name or type. On screen a
diagnostic is two lines, the header and the message clipped to 39 characters:

```text
E010 TEST.N8 3 11
CHARACTER LITERAL NEEDS ONE CHARACTER
```

`NAME.ERR` holds one full line per diagnostic: `E010 TEST.N8 3 11 CHARACTER ...`.
It is scratched when compilation starts and created only if a diagnostic occurs.
After 20 errors the next one is replaced by E221 and compilation stops.
