Executable

Hi. I read on GNU Prolog’s website (http://www.gprolog.org) that the 
simplest way to obtain an executable from a Prolog source file prog.pl is to 
use:

$ gplc prog.pl

This will produce an native executable called prog which can be executed as 
follows:

$ prog

I did that on Linux, but after I typed in prog, nothing happened, I just got 
the system prompt. I was wondering what I need to do to fix that. Also, I’m 
using GNU Prolog on Windows XP and I’d like to produce an executable Prolog 
file, how would I do that?

Thank you.

Mike Webb
