well thanks I now understand the region settings.
About the dem - could it be some error ?!? I downloaded it from esdi .
It is srtm data. I included the srtm geotiff in one of my post could
someone try out the dem for me and see if it works ? I can see there
are areas below 20 degrees and that should be reported by r.mapcalc !

Thanks a ton,
I got it right this time.
Actually it was the g.region problem.
One more thing. I donot know whatz the problem , I generate the slope
and get a whole lot of negative values. Now what are these ? values like
-34.5 and so on ! Well is the dem alright to start with. Set's me
wondering ?!?!
Have you imported a lat/lon dataset into a non-lat/lon location?
what does this say:
GRASS> g.proj -p
GRASS> g.region -p
that might explain the crazy slope values.
