What are the best practices for working with binary data? If I read a
span of binary data, say, into $packet like with read() below
my ( $packet_size, $packet );
read( $client_socket, $packet_size, 4 );
$packet_size = unpack( "N", $packet_size );
read( $client_socket, $packet, $packet_size );
then how should I best access arbitrary ranges of bytes within that
block of binary data held by the $packet variable?
For example, put the first byte from $packet into one variable, the
second byte into another, the third through 18th into yet another, and
so on?

Lars
