Hi to this list and some issues.

[Manuel Gutierrez Algaba]

Hi,
        I'm new to this list and I'm retaking prolog, after many years.
I'm the maintainer of Crosswords for Linux (http://crossword.50g.com), and 
I've been searching for a crossword generators, but all I've found are 
SWI-compatible and I can't run them on gprolog. 

a) Is there any way of loading libraries or something to make them run ?

Besides, I'm trying to do a bit of string processing, but since I'm new to 
the language and the documentation I have is very spartan , I can't guess how 
to :

b) Having these facts: 
   def ( IP , ' Internet Protocol').
   def ( ICMP, ' RFC 792,  part of the IP protocol).

 Considering that IP is a defined term and it's present in the definition of 
another term, I'd like to generate the facts:
  related(ICMP, IP).

 I do need string functions. 


c) I'd like to have more gprolog program examples.
