Here's most of it. You'll have to take care of your own initializing and
looping,
but the basic parts are here.  (This is good for 1296 combinations, as opposed
to your 100 and 256 for decimal and hex. Suitable changes to the constant and
the IfGT value can make this good for an almost arbitrary number of
identifiers.)
