Hello,
Since this afternoon, I have searched and I have find a more recent
shapefile library in gdal project. And in the gdal version, the character
field can be written with a length longer than 255, but it is read as it
have a length codded only on the first byte.
So, what's happenning ? What is the rule ? Why theses exceptions for
character fields ?
In
http://trac.osgeo.org/gdal/ticket/1202 Frank W. said that there were a
fix in shapelib, but I don't see any release after 1.2.10 in april 2003. If
a more recent shapelib exists, where it is ?
Thanks,
Jérôme Cuinet

Subject: [Shapelib] Character field longer than 255
Hello,
Contrary to Xbase (.dbf) File Format Description
(
http://www.clicketyclick.dk/databases/xbase/format/), with Shapefile
library we can add to a .dbf file a character field with a length longer
than 255 character. Is it an extension to dbf file format or an unique
shapelib specification ?
I want to use this function, but I'm worried about compatibility with other
shapefile drivers. Should I use these only for my program, or I could use
these shapefiles with another programs ?
Thanks
Jérôme Cuinet
