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.
