Hello raghuprasad241, I have a different approach for you. Previously, due to some hole in your input data that i have to go through all the trouble to make that big code. Now you have a much nicer input so we can make it look like this.

#!/usr/bin/perl
use v5.10;
use strict;
use warnings;
sub tranpose(@);
my @row;
my @sorted;
while(my $line = <DATA>)
{
   push @row, [split(/\s+/,$line)];
}                        

@sorted = map   {
                    my $in = $_;
                    [map {sprintf("%6s",$_)} @$in];
                }                                #Reformat before prin
+t                           
                tranpose                         #tranpose back to ori
+ginal form                    
                map {[sort {$a <=> $b} @$_]}     #sort each column
                tranpose @row;    
                                  
map {print @$_,"\n"} @sorted;
sub tranpose(@)
{
    my @out;
    foreach my $j (0..$#{$_[0]})
    {    
        push @out, [map {$_[$_][$j]} (0..$#_)];     
    }
    @out;
}

__DATA__
1014    1       10
1015    51      100
1016    11      50
1017    101     999

Output:

  1014     1    10
  1015    11    50
  1016    51   100
  1017   101   999

Hope this help!
