Hi Monks

I have following code 

use strict;
use warnings;
use File::Slurp;

my $abc = 10;

open (IN,'>c:/temp/text.bin');
binmode(IN);
printf IN "%c", $abc;
close (IN);

write_file( 'c:/temp/text1.bin',  pack ('C*',$abc) ) ;

[download]

I expect (Or i am not aware) that text1.bin and text.bin file content is same. When I open text.bin in the hex editor I see '0A' which is correct. I want to convert the perl scalar into binary values and store in a file. But text1.bin content is '0D 0A' which is not i want.

What is the pack format for printf's "%c" ?

Sorry, I could not find by myself. If you could enlighten me with some background documents, It would be a great help. Thank You.
P.S: I am new to bit manipulation in perl.

Thanks & Regards,
