Hi,
Actually, my script will be read two standard input and captured anum and bnum values. After that, gets ano, bno and bcode from chg_indicator.hdb files.
If anum startswith ano and bnum startswith bno then return the bcode and do some calculation based on the bcode. Finally, print the calculation report.
But, I think my scipt is not intelligent enough, could somebody give some ideas on that ?
It always reading chg_indicator.hdb files for each anum and bnum entries.... 
#!/usr/bin/perl -w

my $template = "A12 A4 A20 A20
                A2  A2 A2  A2
                A12 A4 A24 A24";

my %bcodedb = ();

while (<>) {
  my $input = $_;
  my @a = unpack($template, $input);
  my $anum = substr($a[2], skip_zero($a[2]));
  my $bnum = substr($a[3], skip_zero($a[3]));

  open (F, "cat mnta2/bmp/table/smsc/chg_indicator.hdb |");
  while (<F>) {
     chomp;
     next if $_ =~ /^#/;
     my ($ano, $bno, $bcode) = split(/,/);

     if ($anum =~ /$ano/ && $bnum =~ /$bno/) {
            $bcode->{ count }++;

            if ( defined $bcodedb{$bcode} ) {
                 next;
            } else {
                 $bcodedb{$bcode} = "BCODE";
            }
            last;
      }
  }
  close (F);
}

while ( my ($l, $k) = sort each(%bcodedb) ) {
        my $a = $l->{ count } || 0;
        print "Total calls for Billing Code [$l] : $a \n";
}

sub skip_zero
{
        my ($a) = @_;
        my $j = 0;

        foreach my $i (split //, $a)
        {
                return $j if ($i > 0);
                $j++;
        }
}
