AN 8 byte Hex number (FFFFFFFFFFFFFFFF) is a LOT bigger than an 8 digit decimal number.

Even if you store only 0-15 in each location an 8 nibble hex number (FFFFFFFF) is 43 times bigger than your 8 digit number.

Do you JUST want to convert an 8 digit BCD number into its binary equivalent, or into "alphanumerics"
