[GRASS-user] How to change vector category values?

[Thomas Adams - NOAA Federal]

List:

I have 31 river basins (vector areas) with randomly assigned cat values; I
would like to assign the cat values to something more meaningful to me,
namely, I want the cat values to reflect upstream to downstream
computational order when modeling. How do I re-assign the cat values?

Thank you,
Tom
