Hi Monks;
I need really help on this code!
I need to display a long text file and only show, lets say 100 lines of this file at the time, I just can't figure it out where my problem is at this point.
Here is what I have:
#!/perl/bin/perl

use strict;
use warnings;
use CGI qw/:standard/;
use CGI::Carp qw(fatalsToBrowser);
use File::Find;

print header();

my $v_file;
# get the last $pos from somewhere
# It should read lines from any text file.
my $path = "testme.txt";
my $pos = 0;
print "Just to see the value of:***$pos ****";
open VIEWFILE, "< $path" or die "Can't open $path: $!<br>\n";
seek (VIEWFILE, $pos, 0) or die "Couldn't seek to $pos: $!<br>\n";

my $n_counter = 0;
my $count = 100;
while( defined($v_file = <VIEWFILE>) and $count--) { 

    print "<div  STYLE=\"font-family:  Courier, 'Courier New', monospa
+ce; font-size:.7em;\">$v_file</div><br>";
}
if($v_file){
print "<br><center><a href=\"parse_test.pl?pos=$pos\"><font color=#ad0
+000><b>more >>></b></font></a></center>";
}else{
    print "End";
}
# save $pos somewhere for the next page view
#How actualy save this, where could I do this?
$pos = tell(VIEWFILE);
close VIEWFILE;

Thanks for the Help!
