Dear GRASS users
Excuse me as I am asking the same question again. May be last time I didn't
ask it clearly or I am terribly out of touch 
Is it possible to represent missing values in a grass vector point map?
So that while doing calculation (like interpolation from vector to raster)
the point having missing value is skipped.
Thanks in advance.
With regards
Suprit

I think the best way would be to use a special column value or a whole
column for whether vector points are to be counted as missing or not.
Then when you want to do a calculation on non-missing points, extract
them with v.extract
