 I need some help with this one.

I'm trying to write a perl script to interpret hex memory dumps.
How do I deal with hex numbers and shifting and bitwise anding, I'm
getting confused, I have perl 3.0, patch level 12, Vax 6420.

I fed "B000" to a perl script that did something like this:
$word = "B000";
print ($word & 0xF000) >> 12, "/n";
and I get 0.  How come I didn't get B?

Any help is greatly appreciated.
