Ok. But then again I can not use a tuple as an index which would have =
been natural for me to be able to with a datatype of this nature. So =
does the statement

if col[ColType] =3D=3D IU32:

where ColType is a tuple does not work. It is counter intuitive but I =
guess I have to get used to not using tuples.

Thanks anyhow.
