The file I have is only the old symbols and it is a list of 590; like below (minus the spaces)

A.TL5E001100.TAV

A.TL5F001560.TAV

A.TL5T001240.TAV

A.TL5E001230.TAV

A.TL5E001270.TAV

So A.TL5E001100.TAV needs to change to +TL\E5C1100.TAV, A.TL5F001560.TAV needs to change to +TL\F5C1560.TAV, etc

I rewrote the code to be a lot simpler and only did one substitution just so I could see what the output is. Now it runs, but I get no output so I need to read up on matching and substitution string syntax. 

use strict;
use warnings;

my $input = 'TAV.stock.opt.oldsym.txt';

{

  unless(open(INPUT,$input))                           
  {                                                    
      die "\nCannot open $input\n";  
  }

    <INPUT>;
    
    my @lines;
    
    while(my $line = <INPUT>)
    {
    
      chomp $line;
     
     if ($line =~ m/^A.TL5E00/)
     
     {
     
     $line =~ s/A.TL5E00/'+TL\E5C'/g;    
     
     }
     
    }     
    
    close INPUT;
    
    foreach my $line(@lines)
    {
       print $line,"\n";
    }    
    
}
