My understanding has always been that there is = no limit=20 on how many columns you can have in a single row
but i've just read Arin's, WTF is a sup= er column post=20 again and i got the impression he was saying that if its a normal
row i.e not Super, there is a limit but if the = said=20 row=A0is within a structure of type Super then there is a potentially=20 unbounded
amount of columns to be had.
=A0
Is my original understanding correct, have i ju= st=20 misinterpreted his article?

Courtney
