Hello PerlStart, and welcome to the Monastery!

open('FILE',$srs) or die $1;  

while(<FILE>)

Let’s assume for the moment that $srs is a text file. Here are some things to consider:

• 'FILE' is a string, but FILE is a typeglob, which is a different entity. Remove the quotes from around FILE in the open statement.
• $1 contains the first capture from the last successful pattern match. I think you meant $!, which contains the last system error.
• It’s better practice to use lexical filehandles and the 3-argument form of open:
  

  open(my $FILE, '<', $srs) or die $!;

But $srs is not a text file, it’s Word file, so you can’t read it this way at all! You need a suitable CPAN module. Not my area of expertise, but a quick search turns up Text::Extract::Word, which looks promising.
