    Nope, that converts the string in the wrong byte order. that won't work at all. Note that '$1' and '$2' were bytes from a file, not integers from a file?

      Ah. OK. Is the string always two chars long?

      $number = hex("0x". reverse $string);

        I think you need to do some reading. reverse doesn't work how you think either... reverse "ab" is "ab" ... sorry.

          A reply falls below the community's threshold of quality. You may see it by logging in.
      I also checked... presuming the $string was "6801" instead of "\x68\x01" to see if it would work anyway... it does not. try it... 
      perl -e '$i = hex("0x6801"); print sprintf("\%x", $i), "\n"'

      Still wrong. It should return 168, not 6801
