Hex to Binary Conversion routine

Does anybody have a Hex to Binary proc already written.  I know I could do it by parsing out the input string and then using a big case statement, but I'm sure there's a better/quicker way.  Also, I don't really have time to write it in the next few days.  I'm running ksh on an aix box.

I can't rember where I found this but I think it will do what you want (and more).
