Hello Monks, I'm trying to troubleshoot this code that is suppose to supress a line once it finds a string within a string. I would use regex pattern but I prefer to use INDEX unless if there is a perfect way to use it in the code. I tried to read the file with the script but it keeps failing with "Use of uninitialized value" I'll appreicate if you could let me knowhwat I need to chnagei the code to make it work. Thanks in advance. 
#!perl -w

use strict;

my $buffer="";
my $suppress = 0;

my @field;
my %newline;
 # my %partofblock;

my %skipaccount;
$skipaccount{$_} = 1 for qw(77403 77404 77406 77407 77408 77409 77411 
+77412 77413 77414 77416 77418);

 
my $infile  = 'c:/rx_q.008';
my $outfile = 'c:/ftpscript/idxfile.txt';
   
   
   open IN, "<$infile"  or die "Couldn't open $infile, $!";
   open OUT,">$outfile" or die "Couldn't open $outfile, $!";


$newline{$_} = 1 for qw(MSH);

   while (<IN>) {

   chomp();

 if ($newline{$field[0]})  {

       processbuffer();

  } 

  if ( index($newline{$_}, $skipaccount{$_}) != -1) {

        $suppress = 1 if $skipaccount{$field[7]};

  }
 
   $buffer .= "$_\n";      
}
processbuffer();


sub processbuffer {
  print OUT $buffer unless $suppress;
  $buffer="";
  $suppress = 0;
}
