Autofill a b c d aa ab in Excel

Hello,
I remember that excel could complete a sequence is we gave it the first elements.
In this case I'm writing in three different cells (same column) A, B C and I want excel to do the rest as I drag it down: D E F and so on. But if do it I get A B C again...
Is there anything that i have to do??
I'm using Excel for mac 2011
Thanks in advance,

Answer:

Use the formula =SUBSTITUTE(ADDRESS(1,ROWS(A$1:A1),4),1,"")

(for formulas, depending on your country, you might have to change ; with , or the opposite
