I couldn't find the right paper, but I did find the error message for
the BDE saying the Answer table is limited to 255 fields. Aage's
suggestion to increase the block size is good, but won't get around
The BDE *will* use Paradox tables for intermediate data storage, such
as query results, so to be able to show all 300 fields in one dbgrid,
you will have to use a different path.
