Thanks for the info. I didn't know about the assoc and ftype. Looking at the
output of these two commands, I see that my system is set up correctly.
So, I still don't know why the grass.parser() is not working for me. I even
modified my program to use pdb to see what is happening. The debugger is
aborted right after I reach os.execvp("g.parser.exe", [name] + argv) in
grass.py. But if I use "python
c:\osgeo4w\apps\grass\grass-6.4.0svn\scripts\m.dipslope.py --help", I get the
expected results.
