On the fly.

It's internal.  Furthermore, the information you would need to
calculate distance to/from your location, i.e. latitude/longitude of
DXCC entity, state, Grid or IOTA, is internal to the program as well
(embedded within the country file).  There's no way to extract that
information.

No but you could Google it:

It would only be useful with grid squares, unless you have tables of
geographic coordinates for the above-mentioned locations, and
understand the DX4WIN priority for deciding which set of coordinates
to use:

1.  Grid
2.  IOTA
3.  State
4.  Entity ("Prefix")
