Hi. I've been looking at the use of Prolog as a scripting language in
the situations Perl is used --- to try & replace Perl.

For what?... What is missing in Perl that Prolog could provide?...

A.L.

Recursive lists. Completeness. Declarative semantics.
Mebbe I don't know enough about Perl,
but it also seems much finer-grained.

What "finer-grained"?... Perl or Prolog?...

Then see "Higher Order Perl: Transforming Programs With Programs",
book by Mark Jason Dominus. Chapter 9 is about declarative
programming.

Table of content and more information you can find here:

Among other things, Perl has very powerull regular expression system
that is part of the language
(http://www.perl.com/doc/manual/html/pod/perlre.html), recursive lists
(http://www.perl.com/doc/manual/html/pod/perllol.html) associative
arrays (http://www.comp.leeds.ac.uk/Perl/associative.html) and many
features that definitely can be programmed in Prolog if you invest
enough time... And by the way, it has also CPAN (Comprehensive Perl
Archive Network, http://www.cpan.org/) with hundreds of modules that
also could be programmed in Prolog if you have enough time

About logic programming in Perl vs. Prolog see here

http://www.perl.com/lpt/a/967

and Prolog in Perl is here (well.. sort of...)

P.S. I am not fan of Perl, actually I hate Perl, but hate or not, I am
using the best tool to do the job. I have written substantially more
lines of code in Perl than in Prolog.
