Try (Field.Dataset as TwwIBOTable), instead. This makes sure that you
are pointing to the TwwIBOTable component that your are using. Jason
derives from TDataset not TTable. By using TTable in this instance, you'll
compile the code for the BDE, which you do not want, since it increases
your executable's size.

Sorry, I can't help you here. I never used IndexDefs.

Reply:
Are you talking about Calculated fields or Lookup fields. I never
seen the Links tab when only using Calculated fields, but I do see it when
using Lookup fields.
