The following command will convert a hex number such as 93 (stored as
HEXNUM) into decimal:

    DECNUM=`echo "16 i $HEXNUM p" | dc`

However on my system (Esix Rel D SysV3.2) at least it won't work on the
output from hd(1) since it barfs on lower case letters.  Is this the
normal way for dc to work?  I guess the following line will be a general
purpose converter but I'm sure there must be a better way.

  HEXNUM=`echo $HEXNUM | tr [a-z] [A-Z]`
  DECNUM=`echo "16 i $HEXNUM p" | dc`
