Visual Prolog 11 preliminary documentation. This article contains preliminary documentation for the upcoming release |

- Constant fact variables that does not change value after initialization.
- New ways to pass arguments. Named, default and optional parameters and functor originals.
- New attribute [mandatoryOut].
- New predicate notErroneous/1->.
- Bitwise and boolean operators **, ++, ...
- New attribute [attribute].
- Attribute [byVal] can now also be used for output arguments [byVal, out].
- New attribute [pack(N)]
- New directive #stringinclude.
- Lazy/late fact initialization is made atomic/threadsafe.
- More compact layout of functor terms on the 64 bit platform
- bit::isSet/2 is handled intrinsically by the compiler ([intrinsic])
PFC
- More encryption support through the classes crypt, cryptHash and bCrypt_api.
- Support for JSON Web Tokens (jwt).
- Support for Password Hashing.
- OLE drag and drop and clipboard support.
- Support for Slim Reader/Writer locks (srwLock)
- New package winHttp_api for client side HTTP/HTTPS operations.
Examples
- jsonWebToken demonstrates how to create and unpack JSON Web Tokens (jwt) and a way to hash passwords.

- dragDropTargetOle that illustrates how OLE drag and drop and clipboard handling can be used.
