Sorry, here is the code again, thanks for your replay! 
my $start = $getdata;
my $end   = $getdata2;

my $dir = '../weblog/';
@ARGV     = ();

die "start must be less than end" if $start >= $end;
die "no dir $dir here" unless -d $dir;


find sub {
   my $numb = (fileparse($_,'.txt'))[0];
   return unless $numb =~ /^\d+$/;
   push @ARGV, $File::Find::name if $numb >= $start and $numb <= $end;
}, $dir;

die "no .txt files found in $dir" unless @ARGV;

while ( <> ) {
$p1="P1 = (inquiry, launch page)\n";
$p2="P2 = (car coverages, endorsements, operators)\n";
$p3="P3 = (notepad, scratch)\n";
$b1="B1 = (my inquiry: auto, home and location)";
$p0="P0 = (local search)\n";
$c0="C0 = (dist search)\n";
$c1="C1 = (state inquiry)\n";
$c3="C3 = (test notepad)\n";

    Just looking at the rule checking, I can recommend putting the rules into a hash: 
    #!/usr/bin/perl -w

use strict;

#  Define substitution rules using a hash. Note that these rules are 
#  stored in no particular order .. if this is very slow, efficiences 
#  can be achieved by changing to an array of hashes, with the most
#  likely rule checked first.

my %Rules =
(
  "p1" => "P1 = (inquiry, launch page)\n",
  "p2" => "P2 = (car coverages, endorsements, operators)\n",
  "p3" => "P3 = (notepad, scratch)\n",
  "b1" => "B1 = (my inquiry: auto, home and location)",
  "p0" => "P0 = (local search)\n",
  "c0" => "C0 = (dist search)\n",
  "c1" => "C1 = (state inquiry)\n",
  "c3" => "C3 = (test notepad)\n",
  "h1" => "H1 = (owners and coop search and history)\n"
);

#  Process the input stream.

while ( <> ) 
{
  foreach ( keys %Rules )
  {
    if ( m/iapw_$_/ )
    {
      s/iapw_$_/$Rules{ $_ }/ge;
      print;

      #  Is there only one possible subsitution per line? If so, 
      #  we could use a 'last' statement here to go on to the next 
      #  line.
    }
  }
}

    Your logic for opening up the log files is bizarre and does not compile on my system, but I'll presume that you have that part of the operation working correctly.

    I can strongly recommend 'Learning Perl' from O'Reilly books. Read through that, try as many examples as you can, and you'll be far better off to tackle Perl projects.
