  I'm not sure if I missed this somewhere or if this is very basic and I just 
missed the boat.  I have an elevation map and it has no elevation values associated
with the cats file.  In fact, I have brought files in from DEMs and from xyz values
and never have any elevation values associated with the cats file.  For example,
a cat file looks like this:

# 1420 categories


0.00 0.00 0.00 0.00
0:no data

When I do r.slope.aspect it must be using the values between 1 and 1420 to do
the calculations and not the true elevation data.

How do I get the elevation values?  Help, please!
