Dear list:
Here I go again. Thanks for the previous replies. I was able to move around and see my images clearly now. I am also doing on-screen digitizing.
However, I would want to know how to see the attribute data table of the polygons I digitized. Also, how can I edit and add fields in the attribute table?
Thank you for the help.

Vector data:
Try d.what.vect to view, or 'd.what.vect -e' to edit. If you can install
QGIS, this might be easier to work with. To view a .dbf database load into an
OpenOffice or use the 'dbview -bt' utility.
Add fields in v.digit [5.7] from settings->table.
Raster data: [5.0/5.3]
v.support
[5.7] ??

Dear Dr. Hamish & the list:
Thank you for the replies.
I am still confused how to see the attribute tables. In a commercial gis i once used, the attribute table is generated automatically after creating a polygon. There is a command option to open the attribute table and the table will pop-up when selected. The attribute table will have at least 2 important fields, feature unique id number and type. From there, I could add fields according to my data. However in using grass5.0.3, I still don't know how to open the attribute table. Is it generated automatically? Do I need to create and link a separate tabular data file?
I ran d.what.vect with the vector map containing polygons but the result was a warning and failed to see a tabular attribute data. I also ran v.support and was asked to enter values and names of categories. Still, I failed to see a tabular attribute data. I ran several routines but failed.
May I request someone from the list to provide me with idiot-friendly instructions on how to open the attribute table. Also, may I request websites where I could do some reading on attribute tables in grass5.0.3.
Thank you so much.

Let me recommend GRASS 5.7.
The vector engine and the attribute management was completely
overhauled. In GRASS 5.0.x/5.3.x you won't find a satisfying solution.
