Until now we had only one code compilation idea that realizes our Prolog VM. With π-WAM we add a second Prolog VM to the same Prolog system, with the aim to use it for specialized tasks. Optimized for speed the π-WAM is very primitive. The compiler capitalizes that code blocks are relocatable. The emulator dispatches π-WAM in/1 and out/1 commands to the usual Prolog read and write predicates. We could demonstrate a is/2 example and a between/3 example.
