I don't think you are thinking this through all the way. :-)

I can't tell what A is, but I would expect it to be a
pointer array to polygons of various lengths. In other
words, these are the shapes you are trying to put into
the file. But, in any case, you are not even storing the
vertices of *anything* in this file. In other words, at
the very least you have to set:

entnew[j].VERTICES = a_polygon_of_some_sort

You have nothing like that there. What do you have
in A? Where are your polygons that you are trying
to put into the shapefile? What do you think the
BOUNDS fields should be set to? What values? What
are you putting in there?

Too may open questions here to expect much success yet.

Cheers,

David
