I declared the variable at the top of my code so it should be global: my $public_key_type; I have other blocks that are configured the same way that work without issue in the first loop. I also have "use strict"; and "use warnings"; The below block of code works with all the loops my code does I have. 
=====================================================

          if  ( $line =~ /^Serial number:/ ) {
            $serial_number = scalar <DATA> for 1; 
               $serial_number =~ s/^\s+//;                
            $serial_number =~ s/\s+$//;           
            $serial_number =~ s/\R//g;
            $serial_number = "'$serial_number'";
                            
                    
    }
