See pack patterns "n" and "v" instead, or the "<" and ">" modifiers if you really want signed interpretation.

$ perl -le 'print unpack("v","\x03\x50")' 20483 $ perl -le 'print unpack("n","\x03\x50")' 848 $ perl -le 'print unpack("s<","\x03\x50")' 20483 $ perl -le 'print unpack("s>","\x03\x50")' 848

    Awesome!! The use of "n" pattern worked great.
