Easy solution is to use an index on the data.

Then if I understand you correctly, you want it look like this:

00,01,02,...,09,0A,0B,...,9Y,9Z,A0,A1,..., etc

This is a guess but here might be a good way to do that:

Make a string:

string="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"

Then you need two counters:  first(2,.0), second(2,.0)

first="1";second="1"

Guess=mid(string,first,"1")&mid(string,second,"1")

check the index for GUESS.

if "I do nto find a match"  then "I GOT A NEW CODE"  stop here.
if "I find a match" then second=second+"1"
if second gt "36"
	then: first=first+"1";second="1"
if first gt "36"
	then: I am done

Very rough logic but this will do it.  just order the string the way you 
want it to cycle past the values.
