Found another example that doesnt store the entire file in a variable but reads it line by line like this, 
open ( my $input_fh, "<", $input_file );
open ( my $output_fh, ">", $output_file );
foreach my $line ( <$input_fh> )
{
##########  

i have to use regex here to first see if this line start with a HDR - 
+correct?
  then if it does i would do a substring to delete the first 50 and wr
+ite the
  rest to the output file
else 
  write the entire line to output
similarly check if it starts with EDR and substring again
##########

}
close ( $input_fh );
close ( $output_fh );

I didnt quiet get your suggestion on using the line number and eof. The file will have numerous records that has headers and footers. Am I on the right track with the above approach? Storing in a variable vs reading line by line. Is one way better than the other?
