PBXB64 is a native Windows x64 multi-frontend compiler written in C. Its registered language frontends share the compiler IR, optimizer, x64 backend, object writer, and linker.

| Frontend | V15 qualification boundary |
|---|---|
| PowerBASIC-compatible BASIC | Qualified for the registered test surface; this is not a claim of complete PB11 parity. |
| B64 | Compatibility-qualified and frozen to its documented surface. |
| C | Partial C17-oriented frontend with known floating-point integration gaps. |
| x64 Assembly | Qualified standalone and inline assembler surface. |
| PILOT | Compatibility-qualified PBXB64 dialect, including A, U, S, arithmetic, and V bridges. |
| FORTH | Partial frontend with 174 source-registered primitives and parser-handled control/definition words. |
| COBOL | Bounded native subset; not a complete COBOL implementation. |
| Rust | Qualified for the documented V14-compatible subset. |
| Logo | Complete V14 object contract; runtime remains separately unqualified. |
| SPR | All documented routes exist; runtime and bridge qualification remain bounded. |
The English and German source trees contain the same 2,775 topic filenames. Each compiled CHM contains both complete trees, with this language as the default. Frontend status statements are derived from live source registration, canonical tests, and current component status. Help text alone is never proof that a behavior is implemented.
