Hi all, I made those changes here...actually copied from the old file and made changes to it. I did follow your advice and changed it but didn't upload the file with those changes.:) Ok..I struggled with it and found that if i read the file as an array as shown below in the code I was able to read each line in the file but not with Tie::File. Can some one tell me the reason? 

#!/usr/bin/perl 

use strict; 
use warnings; 
use Tie::File; 
use Fcntl; 

#Variable Declaration
my @array; 
my $line=""; 
my @data; 
my $map_dir=""; 
my $dir=""; 
my $part_no=""; 
my $chg_lvl=""; 
my $int_lock=""; 
my $t_spec=""; 
my @list=""; 
my $formatted_list=""; 
my $i;

#Program Main 
if ($#ARGV == -1)
{ 
    print "\n";
    print "Enter a file containing part number, <R> to Quit: ";
    chomp($file_name=<>);
}
else
{
    $file_name=$ARGV[1];    
}


open (FILE,"$file_name"); 
########## 

These two lines are commented out 

################### 

#tie (@data,'Tie::File',$file, mode=>O_RDWR) or die "Can't tie to $fil
+e:$^E\n"; 

#(tied @data)->defer; 

############## 

##I am reading the file as an array here 

################ 
@data=<FILE>; 
foreach (@data) 
{ 

($map_dir,$dir,$part_no,$chg_lvl,$int_lock,$t_spec) = split /\s+/; 
print "@list"; 
print "$formatted_list"; 
print " $map_dir,$dir,$part_no,$chg_lvl,$int_lock,$t_spec"; 

} 

#(tied @data)->flush;

So is there a problem using Tie::File? Thanks
