Thnx, I've fixed it (without OO). If I try OO, like:
#! /usr/bin/perl

use strict  ;
use Fcntl 'SEEK_SET'; 
use IO::File ;

my $fh = new IO::File ;

$fh->open("fio.pl") ;

$fh->binmode() ;
$fh->setpos(4) ;

my $in ;
$fh->read($in,2) ;

printf "result: %s\n",unpack("A2",$in) ;


$fh->close() ;

[download]
The output is: result: #! (thats no shift at all!)
But I get the idea that the biggest mistake has been made with the read command....
Also, what about perldoc IO::Handler:
$io->read ( BUF, LEN, [OFFSET] )

[download]
I miss the explanation of the 3 variables BUF, LEN and OFFSET ?

Thanks
Luca

update: solved the seek issue: $fh->seek(5, SEEK_SET) ;
I guess the only thing I don't understand is the OFFSET. If I give that a number I get nothing... ?
