I'm not quite sure what you're asking for. If you just want to print out all the values of $a as their hex values, then 
my @bin = unpack 'C*', $a;
$a = '';
for (@bin) {
   $a .= sprintf ' 0x%02x', $_;
}

should do it. The coding style is pretty hard to get through (and you can get some pointers from the monks here if you'd like), but one thing that stands out is that you open "OUT" twice, without closing it.

Update: Woops, fixed unpack spec.
