[GRASS-user] Creating Points Map

   I've an ASCII file of three points. Each is specified by longitude,
latitude, and name. I cannot properly import these to a map so they can be
reprojected and used.

   1) Tried creating a location, placesLL, using the wxPython UI but it would
not let me enter the principal latitude or central meridian. To overcome
this hurdle I copied a .prj file from another location (also in LL
coordinates) and specified that for the new location.

   2) From the command line (within the placesLL location and rbs mapset) ran
"v.in.ascii input=/usr4/keypoints/sites.txt output=features format=point
columns='x double precision, y double precision, name varchar(20)' x=1 y=2"
but no primitives were seen or processed.

   What might I have done incorrectly?
