[GRASSLIST:554] Re: line to area

[Richard Greenwood]

Thanks to Erin O'Doherty and John Dougherty for the quick replies. My 
mistake was that I had not labeled my area in v.digit. All I wanted was a 
MASK, so I wasn't thinking about labels. But v.to.rast was expecting a label.

Thanks for the help guys.
Best regards,
Rich
