Dear Casey,

everybody is on holiday, I assume, otherwise you would have been 
overwhelmed with messages where to locate the existing tutorials (or am I 
a bit too optimistic?). Usually, anything that is available can be found 
on the anonymous GRASS ftp-site at moon.cecer.army.mil. When you go 
through the directories, you'll notice some tutorials, the very contents 
of which I don't know - I never used them, in fact. There used to be a 
GRASS Beginner's Manual by Martijn van Leusen - I suppose he is on 
holiday as well - but this may be available in the grass/incoming 
directory. What you *should* try to get is the User's Reference Manual; 
if there is no kind soul around that can tell you how to get it, you can 
always get the online man-pages with g.manual. And to get you started 
with your (admittedly very simple) problem:

- start a monitor with d.mon [monitorname]
- set your geographic region to the map you want to have a look at with
g.region rast=[mapname]
- don't forget to run d.erase
- display your map with d.rast [mapname]
- zoom in with d.zoom (interactive!)
- run d.erase again
- display the map again
- saving to a new file of the zoomed area does not need the displaying, 
but you might want to check; saving to a new file can be done in two 
ways:

	either r.resample [mapname] o=[new_map]
or      r.mapcalc [new_map] = [mapname]

both will 'clip' your old map to your zoom region.

Hope this will get you going!

Philip Verhagen
