I just tested something and found out that the helpfile is incorrect for v.in.ascii (although my often faulty memory was correct).
The helpfile says that you can specify which columns are used for the x and y coordinates. However, this generates an error.
I remembered that in the past, the x and y columns MUST be the the first 2. When we changed our text file to have x and y in columns 1 and 2, it reads the file fine.
We’re doing this with GRASS 6.3 on Windows AND Mac.

this is correct.

what's the error? sample input file?
The error is something about an incorrect number of columns. The file was a
very simple one for just 2 points
Originally
cat, x, y, string
When changed to
x, y, cat, string
it worked fine.
This was compiled from cvs 6.3 last week.

nope, I've never heard of that. I ran it with x&y as columns 2&3 yesterday.

Are you sure the column separator was defined correctly ? Whenever I got
this error this was always the problem.
Absolutely. We used the same column separator and same way of specifying it
in both cases.

It is hard to know why without seeing a sample of the file that fails and the
exact command line used.
perhaps a stray extra or missing fs after the data on some line?
blank-but-for-fs line at the end of the file?
