v.patch output (fwd)

[Bernd Munier]

To  Richard & Lesley-Ann

Yes, you should specify that you want to remove a VECTOR map, why not use
the interactive mode of g.remove, if you are unshure of the syntax?

Regarding the v.digit problem, see below at ***

*** Are you shure, what you have set the correct window, ie. what corresponds
to g.region if you are using v.digit. 

v.digit reads the default window from the header of the actual map, NOT 
from the g.region settings. So, have a look at the border koordinates, map-
projection information, zone number (for UTM) etc. 

Using a digitizing table, you will be asked to point out the display window
on the digitizing table at start-up (after specifying and digitizing ref.
points - check those too! ).

Hop that will help
