[GRASS-user] trouble with dbf under WINGRASS

[Niels Thevs]

Oh sorry, I meant GRASS 6.3. RC4, dating from Jan 15th 2008. Two more 
thing appeared: r.to.vect did not produce a dbf file. When I wrote a 
script as txt file with r.mask, there was an error message: r.mask 
command not found. This happened under Q-GIS with the GRASS shell as 
well as in GRASS.

Best regards

Niels
