>Do you have a copy of Codebook? I'm pretty sure there's a Base36 function in there that could be adapted to what you want.

Yeah, I do. I have looked in the book, because I thought I remembered something like that, but I didn't find it. I also did a search of my codebook projects (using my nifty SearchString tool :-)) and came up with nothing. Do you remember what the function is called?


>Otherwise just take the rightmost char, use asc() to convert it to a number, increment it, if goes over "Z" set it to A and increment the next digit to the left.

I started laying out logic to do exactly this and it got pretty hairy. That's why I was looking for some other creatice solutions...

Thanks for your help.
