Regarding the recent inquiry about Common Lisp & Prolog under VM:
Though we run VM, one of the Virtual machines is UTS -- Amdahl's port
of System 5. Under this we run a locally modified version of CProlog
and are quite pleased with the performance. Warning -- UTS is *NOT*
cheap (but is very nice) !!
Our own Prolog compiler (for VM/CMS) is just nearing completion -- It can
compile roughly half of itself. However we do not expect that it will
be ready for release for a while. It follows Clocksin & Mellish as well
as can be done on an IBM mainframe (EBCDIC-->ASCII conversions and
such). When released it will be *fast* -- roughly 95 KLips on a 4341,
and currently around .8 MegaLips on a 3090 (using one processor!).
I believe the IBM prolog (Waterloo) uses a different syntax than is
commonly used.
Hope this has helped --
