I'm a newbie working only for about 3 weeks in Common Lisp (but I used
Scheme for about 4 months last year)

I have Paul Graham's ANSI Common Lisp, but I don't really understand
the way he explains the loop macro

Can some one try to explain me or tell me some site with that information.

Thanks

Maybe these links will help a bit:

Ola', Gustavo.  Bemvindo ao mundo do Lisp!

You don't make it clear whether you're trying to figure out how to use
LOOP or to implement LOOP.  I'm guessing you just want to use it.  The
following might help:

In the Common Lisp HyperSpec,  at

  http://www.xanalys.com/software_tools/reference/HyperSpec/FrontMatter/

go into the Symbol Index and look for the symbol entry for LOOP, which has 
detailed syntax information.  Also, go into the Chapter Index and look for
Chapter 6.1 (The LOOP Facility), which goes through conceptual discussions
and offers examples.
