Emulating π-WAM in Dogelog Player (Re: Dogelog Player on a A18 Everest)

Show key headers only | View raw

Hi,

We are currently setting sail to give Dogelog Player
a more janus faced backend. 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.
