From:  Ed Fox 

Can anyone send me a YACC/LEX grammar system for Prolog,
or a translator using those tools that will handle conversions
between dialects of Prolog?  Alternatively, such a routine
written in Prolog is acceptable.

My need is to convert Prolog code written in DEC-20 or similar
Prologs to our HC system that has been under development here
by John Roach et al. Doing it by hand or editor is tedious and
re-inventing the wheel to parse Prolog seems silly, though I
expect to have to add in the HC code generation  part in any
case.

Many Thanks,
