Replace page number with alphabets?

i’ve got a headache over this. I try to change page numbers into alphabets instead(in Excel 2000). Maybe this sounds insane but my printing will only be a few pages… so the limit of the alphabet range doesn’t matter. I can’t find any settings I can set to make this thing work. Does any of you know how to do it? using VBA? is there any settings I have over looked? if this even possible? Please help..
