Thank you for spending the time to reply to my request.  I tried
your suggestion.

s.in.ascii  worked fine as far as I can tell (once I worked out
that I had to make my Latitude values negative for the Southern
Hemisphere).  A line in the file looks like:

        146.005|-19.5|313

However, (isn't there always an however :-) I can't get s.menu
to work in the way I require.  I choose option 6 "Convert site
list to raster file (0/1)" and choose one cell per site.  The
resulting raster file seems to only have  zero values for the
elevations.
've tried editing the site_lists file to include a  #
character before the "description" field as suggested in the
manual, so that the line in the file shown above looks like:

        146.005|19.5|#313

This didn't seem to work either.

I checked the current region was correct with g.region.
Any clues?   Is there a problem concerning expressing the LAT/
LONG values in degrees and thousandths of degrees ?
