I've been asked to select a PROLOG system to run on a DEC VAX under VMS.
This is for a commercial project, so stuff which Universities distribute
free for non-commercial use won't do.

I need to know: 
	* What syntax it uses - especially, how like Quintus it is.
	* What the 'foreign function interface' is like.
	* Roughly what the performance is like.
	* What the programmer's environment is like - and how much
		you like using it.
	* How robust it is - and any points to watch...
	* What it costs and from whom (UK supplier if possible ??)

Mail me, and I'll summarise if there's any demand - many thanks, all - Oh,
and one last thought: I can't easily mail to the States - so I can't reply
directly; sorry.
