Which fields belond to Primary Idx?

Hi there folks.

I need to find out which fields from my TTable belong to
the primary index. I know how to find out secondary indexes,
and I also know how to find out if there is a primary index.
But if there is a primary index, I want to find out how many
fields from the beginning are included in the primary index.

BTW: I'm working with Paradox-tables.

Peace,
       Petri
