You do know that there is v.in.region ?

You could start by giving us more information such as
- how do you launch this script ?
- what is the result ? I.e. for example if a map is created by the script, what is the v.info, and possibly v.category option=report output for this file ?

Yes I don't know v.in.region. My purpose was not to create to something new but
to learn how to create a very simple vector map base on the region attribute.

the script will be launch into grass envir. using v.rectangle output=xxxx for
example and the map is created by the script. Please compile the script and
install it you will have every info.
