> Which Office versions does this 1024 limitation apply to? All?

Excel 97 - 2003.
Not sure about the new beta, earlier versions might be less, I forget. Even
manually you cannot enter or edit a formula starting with an "=" over 1024.

FWIW a formula can contain over 1024, but you cannot read or write it.
