      First open the file and while there are lines in it split them into an array then add this array to your global AoA.
      The relevant commands are open, while, split and push

      We don't do your job, though it looks as though MidLifeXis is doing your managers.

      print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."

        Sorry that I could not post the whole code

        Here is the thing I've tried out.

        Problem is that I'm unable to match the Numbers inside the data. Please suggest the best way to do this

        #!/usr/bin/perl
use strict;

# Array to hold the text file data
my @chunks;

open(CONF, $txtFile) || die "cannot find the text file\n";

while(<CONF>){
    chomp;
    if (/^#/){
        # Must be a comment, skip it
        next;
    }
    elsif (/^\s*$/) {
        # Only contains whitespace, skip it
        # could be blank lines
        next;
    }
    elsif (/^M/){
        # Contains dos/mac control characters
        my @lines = split /^M/, $_;
        for ( my $i = 0 ; $i <= $#lines ; $i++ ){
            push(@chunks, $lines[$i]);
        }
    }
    else {
        # assumed to be a normal data line
        # trim trailing and leading spaces for parsing the data later
        $_ =~ s/^\s+|\s+$//g;
        push(@chunks, $_);
    }

    #print "Found data for ", scalar(@chunks), " lines in $csv\n\n";
}

close(CONF);

# Get the Array Index where the 'Summary of This Bill Period Charges' 
+text is located
my $index = indexArray('Summary of This Bill Period Charges', @chunks)
+;

# skip next 4 lines
$index = $index + 4;

foreach ( $index .. @chunks ) {
    if ( $data =~m/(\d+)\s{2,}(\d+)\s{2,}((\d|-)?(\d|,)*\.?\d*)\s{2,}(
+(\d|-)?(\d|,)*\.?\d*)\s{2,}/ ) { print $5; }
}

# Thanks to a post which gave me this snippet
sub indexArray{
    my ($text, @data) = @_;

    for( 1..@data ) {
        ;
        if ( $data[$_] =~ m/$text/ig ) {
            ;
            return $_-1;
        }
    }

    -1
}
