I'm in need of some help from all you experts out there....

I have a table of polylines (from a GPS receiver) that represent boundaries
of an agricultural field. These lines are not continuous but are only drawn
where the boundary of the field changes direction. So at the moment to draw
the field and get an area I trace round the polylines (using autotrace) with
the polygon tool - drawing a straight line between the polylines.

Is there any way to do this automatically in mapbasic if I select the
polylines to combine or if they have a common attribute?

I have tried combining the polylines into 1 and then using "convert to
regions" in the edit objects menu but this draws regions by closing the
original polylines - i.e. creating 4 regions from 4 polylines not 1 region
from 4 polylines.

Anybody have any ideas?
